Amazon temperature gun

Amazon temperature gun DEFAULT

You’re positioned over the grill with a variety of steaks, chicken pieces and sausage links sizzling away before you. The problem? They all cook at different rates and need to reach a different temperature to achieve optimal doneness. Now you could drag out a normal thermometer to poke and prod each one to discern its given temperature or you could take a 21st-century approach and try a laser thermometer.

Not only is this style incredibly fast and accurate, but because there’s no traditional probe you don’t have to worry about getting dangerously close to a hot fire in order to get a reading. Better still, there’s no fear of cross-contamination between different foods as nothing has to be inserted from one piece to another, causing those precious juices to flood out in the process.

Here, we’ve rounded up four of the best models available on Amazon so you can get cooking like a pro.

1. Etekcity Lasergrip Digital Infrared Thermometer

Fast, accurate and easy to use, Etekcity’s model is top of the line. The innovative design uses an infrared beam to take the temperature of a given food from between 14 and 17 inches away—plenty of space to prevent you from getting too close to an open grill flame. And thanks to a large and illuminated LED display, it’s easy to read whatever temperature pops up. Capable of taking readings in both Fahrenheit and Celsius, the user simply takes aim and pulls on the trigger to operate. Though many bonus cooking tools can fall by the wayside, we think the bright yellow detailing on this example will keep it from getting lost in the back of a drawer.

2. SOVARCATE Infrared Thermometer

With a look so rugged and streamlined, this sleek model looks like something right out of a military toolkit. Its substantial housing feels secure in the hand and its laser can accurately read the internal temperature of an item ranging from -58 degrees-Fahrenheit all the way up to a sweltering 572 degrees-Fahrenheit. But don’t think it’s limited to food alone. Its ability to take temperatures from a distance also makes it an ideal choice for testing the temperatures of machines, appliances and work equipment to make sure everything is operating smoothly.

3. ThermoPro Digital Infrared Thermometer Gun

With this model, applications are endless. Not only can it get accurate temperature readings from things ranging from brass to ice to frying oil, but it can also determine a range of temperatures in a single item, like the water in a pool or hotspots in a pan. Crafted from bright orange material, it is tough enough to withstand regular use and also easy to find thanks to its bright colorway. Its energy-efficient design operates on two AAA batteries that fuel its laser in addition to its easy-to-read LED display.

4. Inkbird Laser Temperature Gun

When speed is of the essence, Inkbird’s infrared thermometer gun delivers. It displays the temperature of your meat in just half a second,  Featuring the latest sensor technology, it can measure temperatures between -58 degrees Fahrenheit up to 1,022 degrees Fahrenheit and promises a high accuracy of plus or minus two percent. The distance to spot ratio, meanwhiles, sits a 12:1, which means you can measure your ingredients at a longer distance. The gun is also equipped with a colorful display and LCD backlight that allows you to see the temperatures even in the dark.

Exclusive: Amazon deploys thermal cameras at warehouses to scan for fevers faster

(Reuters) - Inc has started to use thermal cameras at its warehouses to speed up screening for feverish workers who could be infected with the coronavirus, employees told Reuters.

The cameras in effect measure how much heat people emit relative to their surroundings. They require less time and contact than forehead thermometers, earlier adopted by Amazon, the workers said.

Cases of the virus have been reported among staff at more than 50 of Amazon’s U.S. warehouses. That has prompted some workers to worry for their safety and walk off the job. Unions and elected officials have called on Amazon to close buildings down.

The use of cameras, previously unreported, shows how America’s second-biggest corporate employer is exploring methods to contain the virus’ spread without shuttering warehouses essential to its operation.

U.S. states have given Amazon the green light to deliver goods with nearly all the country under stay-at-home orders.

In France, Amazon has closed six of its fulfillment centers temporarily - one of the biggest fallouts yet from a dispute with workers over the risks of coronavirus contagion.

Other companies that have explored using the thermal camera technology include Tyson Foods Inc and Intel Corp. The camera systems, which garnered widespread use at airports in Asia after the SARS epidemic in 2003, can cost between $5,000 and $20,000.

This week and last, Amazon set up the hardware for the thermal cameras in at least six warehouses outside Los Angeles and Seattle, where the company is based, according to employees and posts on social media.

Thermal cameras will also replace thermometers at worker entrances to many of Amazon’s Whole Foods stores, according to a recent staff note seen by Reuters and previously reported by Business Insider.

The company performs a second, forehead thermometer check on anyone flagged by the cameras to determine an exact temperature, one of the workers said. An international standard requires the extra check, though one camera system maker said the infrared scan is more accurate than a thermometer.

How widely Amazon will deploy the technology at a time when camera makers are grappling with a surge in demand could not be determined. A Whole Foods representative said cameras ordered weeks ago were starting to arrive for use.

Amazon confirmed that some warehouses have implemented the systems to streamline checks. The company is taking temperatures “to support the health and safety of our employees, who continue to provide a critical service in our communities,” it said in a statement.

Early this month, Amazon said it would offer face masks and start checking hundreds of thousands of people for fevers daily at all its U.S. and European warehouses. Associates walk up to a Plexiglas screen, and an employee on the other side scans their forehead by pointing a thermometer through a small hole.

That process has not been without challenges. A worker performing temperature checks in Houston said his proximity to associates made him uncomfortable, in spite of the screen separating them.

“I didn’t sign up for this,” he said.

A Los Angeles-area employee, who also spoke on condition of anonymity, said a line once formed outside her warehouse, and employees could not receive masks until after they had entered the building and had their temperatures taken.

The thermal camera system is faster, two other workers said, with no stopping in front of a screen necessary. The cameras connect to a computer so an employee at a distance can view the results, one said.

Amazon did not disclose whose gadgets it was using. One of the employees, at a warehouse outside Seattle, said the technology came from Infrared Cameras Inc in Texas. Reached by phone, ICI’s chief executive, Gary Strahan, said he would not confirm or deny his company’s working with Amazon.

Other purveyors include UK-based Thermoteknix and U.S.-based FLIR Systems Inc.

Buy:GoodBaby Touchless Thermometerat25.99

As its name suggests, the GoodBaby Touchless Thermometer is safe enough for infants, but can be used for kids and adults as well. To use: point the digital thermometer about 2-3 inches away from the forehead and press the temperature button to activate scanning. The thermometer uses infrared technology to deliver a reading in seconds. The color-coded system makes it easy to quickly see your temperature and status.

A green light means you’re in the clear. An orange backlight and three beeps means you have feverish temperatures (above 99.3°F). The digital thermometer will flash a red light and sound five beeps to warn you of a full fever (above 100.4°F). The numbers are easy to read and understand. You also have the option of switching to Celsius.

The touchless thermometer delivers a more accurate reading than a standard mercury thermometer (it’s lot more comfortable and less intrusive too since you don’t need to insert it anywhere). A touchless thermometer is also more hygienic and easier to clean — just wipe down with a damp cloth. The battery-powered design means no wires or charging cables to get tangled up in either.

This set includes one touchless infrared thermometer, one storage pouch and two AAA batteries. The GoodBaby Touchless Thermometer has a 4.7-star rating (out of five) from more than 33,000 reviewers online. See full deal details here.

What you should know

Why you should trust us

When the coronavirus pandemic began and demand for fever thermometers spiked, leading to significant stock shortages, we scoured the internet on a near-daily basis for months to find thermometers—any thermometers—available for purchase. However, we started our search for the best thermometer back in 2016, diving into the recent research on the subject and looking at what the science said about the benefits and drawbacks of each of the different types of thermometers—including the latest studies examining infrared thermometers. Over the years, we’ve spoken to four physicians for their opinions on the best thermometers for at-home use, considering the needs and preferences of both adults and children.

Who this is for

Having a reliable thermometer on hand can provide peace of mind as the coronavirus pandemic continues, as fever is one possible symptom of SARS-CoV-2 infection. A trustworthy thermometer is also useful for any other time you’re unsure whether you or your kid is running a fever. But as with a spare tire or a flashlight, you sometimes don’t realize how badly you need a reliable one until it’s too late. As commenters on previous versions of this review have expressed, many people found themselves at the beginning of the pandemic lacking a thermometer or discovering that their rarely used ones had stopped working. A rapid surge in demand dried up thermometer stock at stores nationwide, while online marketplaces became flooded with all sorts of models, both reliable and not, at exorbitant prices.

In 2020 and 2021, we tested 15 thermometers, keeping in mind that in many cases they would be used for children and adults in a multigenerational household for many years to come. Fever thermometers designed for at-home use don’t need to be recalibrated (in other words, if yours was accurate at the time of purchase, it should still be), so if you have one that fits your needs and still turns on, this isn’t a device that you need to replace constantly.1 But newer thermometers offer features such as faster read times, better displays, fever alarms, silent mode, and memory logs, all of which can make life a little easier when you or a loved one may be sick. If you have a kid or care for one, an upgrade to an ear or forehead thermometer, especially a contactless infrared model, can take much of the struggle out of measuring a temperature.

How we picked

Fourteen thermometers shown arranged on a tan background.

Our requirements for a thermometer are simple: It should be accurate, consistent, and available.

Whereas in previous years of research and testing we could be more selective (prioritizing additional criteria such as speed and features such as large, backlit displays and options to disable sounds), in 2020 and well into early 2021, during a pandemic that upended commercial supply chains, we couldn’t afford to be as choosy. Like everyone else, we were limited to selecting from whatever was in stock at the time. We will continue to monitor the availability of our picks and other promising options.

Types of fever thermometers

Whereas traditional oral/rectal/axillary thermometers have long been the most popular tools to take temperatures at home, forehead and ear thermometers tend to be faster and easier to use, especially with children.

Digital stick thermometers are simple and offer reliable measurements and fast results, but you need to keep your mouth closed around the probe for anywhere between 10 and 60 seconds, and oral measurements may be skewed if you’ve recently consumed something very hot or cold. Using a stick thermometer orally is tough for most toddlers and preschoolers, so such models are recommended for people ages 4 and up. Oral thermometers today usually pull triple duty as axillary (armpit) and rectal thermometers, as well. Although rectal temperatures have long been the gold standard for infants, many countries, including the UK, actively dissuade parents from using the oral or rectal methods at any age due to discomfort with the former and safety concerns with the latter (PDF). The UK now recommends that stick thermometers be used for armpit (axillary) measurements for newborns under 4 weeks and suggests using infrared forehead thermometers for any age above that. The American Academy of Pediatrics still recommends rectal thermometer use for newborns but acknowledges research that shows infrared thermometers are accurate for people over the age of 3 months.

Most thermometers we tested covered a range from roughly 96 °F to 109 °F with an accuracy of ±0.4 degree.

Ear and forehead infrared thermometers, both in-ear/on-forehead and contactless, are accurate enough to properly track a fever and are generally easier to use than stick thermometers. These thermometers tend to be a little more expensive than simpler oral/rectal/axillary models, but they’re worth the investment when speed and comfort are top concerns.

Forehead and ear thermometers both measure temperature based on heat radiated from either the temporal artery (forehead) or the eardrum (ear). Although it is tempting to just place an ear thermometer in an ear and press the button, these thermometers are a little more complicated than “insert and wait,” so make sure to follow the directions to pull out the shell of the ear to line things up. The Mayo Clinic does not recommend ear thermometers for newborns; Mayo advocates a minimum age of 6 months, basically when children are old enough to balk at a rectal thermometer but too young to manage an oral one.

Whereas ear thermometers almost always require skin contact, many forehead infrared thermometers are “no-touch,” contactless models (others require a light touch of the thermometer to the forehead). On the downside, results from these thermometers may be affected by factors such as perspiration and air temperature (taking the temperature itself may not wake up the sick person, but wiping the sweat off their head first might). Infrared thermometers are also more susceptible to ambient temperature: To work properly, they need to be in the same room as the person who needs their temperature taken for around 30 minutes prior in order to acclimate to the surrounding air temperature and provide an accurate measurement.

Demand for contactless thermometers has skyrocketed in the past year. With a pandemic of a highly transmissible respiratory virus ongoing and with restrictions in place, the idea of a no-touch thermometer is particularly appealing—as is the idea of taking a sleeping child’s temperature without disturbing them. Although the technology is still fairly new, it is being widely adopted in clinical, commercial, and household settings.

Most of the thermometers we tested covered a range from roughly 96 °F to 109 °F with an accuracy of ±0.4 degree. Some report lower accuracy at higher ranges, but if your temperature is pushing 107 °F, you’re ideally in a hospital and not at home quibbling over a 0.4-degree difference. Know that the FDA does not test and “approve” home-use fever thermometers itself. According to FDA spokesperson Fallon Smith: “Electronic clinical thermometers marketed in the US are typically tested according to voluntary international consensus standards recognized by the FDA or equivalent methods—we review the submitted data and if the device is similar to another device already on the market we approve it under what is called a 510(k) clearance.” So a device that claims to be “FDA approved,” such as our pick from Mobi and some iProven models, didn’t go through special, rigorous testing by the government—its packaging is simply reporting that the company’s in-house tests fit the guidelines. Recently, some companies, such as ThermoWorks, have started using the term “FDA-cleared,” which still refers to the submitted packaging guidelines, not to the product itself.

Whatever type of thermometer you choose, it is important to remember that as with a bathroom scale, no device meant for home use can provide exact, 100% accurate measurements. At-home fever thermometers are just not that precise (and temperature is not a static measurement). Luckily, this isn’t the goal: Just as how a bathroom scale is meant to track trends in weight gain and loss, a thermometer’s job is usually to track trends over time.

How we tested

Three infrared thermometers shown with their backlit displays glowing.

Among so many other things the COVID-19 pandemic disrupted, it upended our thermometer testing plans. Whereas in previous years we had taken the top contenders to a clinic, where we would compare their readouts with those of a machine often used in urgent-care and hospital settings, in 2020 and 2021 we tested thermometers in situ: at home. I tested each thermometer dozens of times on myself (a healthy adult with no fever), as well as on the three other members of my household (another healthy adult and two healthy kids, none with fevers).

Although all of the infrared ear and forehead thermometers we tested in 2020 and 2021 gave results in less than three seconds, the operating time for the oral thermometers ranged from a low of eight seconds to an excruciating high of 40 seconds (with a few read failures from one especially odious model). A minute may not seem like a long period of time—until you’re sitting around with a rigid stick of plastic under your tongue or, worse, trying to hold it under the tongue of a kindergartner.

Most of the thermometers we tested, including all of our picks, have two alarms—one that tells you the reading is done and a “fever” alarm that goes off if your temperature is above a given level. Most of the alarms alert you to an elevated temperature at 99.5 °F and above. Dr. John Mills, an infectious-disease specialist at the University of Michigan, stressed that even though people often talk about a fever as anything higher than 100.4 °F, “there is no such thing as a normal temperature.” Mills continued, “Everybody has a different personal set temperature as a baseline, and it can vary throughout the day. You can’t pick one point where everyone should worry—99.5 °F and 100.4 °F are reasonable thresholds, but that may not be sensitive enough for people with an increased risk of infection, or may be too sensitive for people who are generally healthy and have a higher baseline.”

To find out how a forehead thermometer worked in the outside world, a tester for a previous version of this guide tried one on a healthy person sitting in the sun. The reading came back as 103.8 °F—a lesson in both thermometer use and the need to sit in the shade. You can follow all of the instructions (wipe off sweat, wait after exercise), but the environment around you will still influence your skin temperature. Engineers at Braun explained that it “takes 28 minutes to adjust to a new setting”—in other words, you and the infrared thermometer need to be in the same steady-environment room for a half hour before it will give you an accurate read.

“There is no such thing as a normal temperature. Everybody has a different personal set temperature as a baseline, and it can vary throughout the day.” —Dr. John Mills

Every thermometer we tried bounced around within a small range from measurement to measurement. In the end, though, most of the thermometers we tested gave readings that were acceptably consistent. Our picks stand out from the pack on the three most important fronts in these strange times: accuracy, consistency, and availability.

Our pick: Vicks ComfortFlex

A Vicks ComfortFlex, our best thermometer pick, with the temperature reading 99.2 degrees Fahrenheit.

For a traditional oral/rectal/axillary thermometer, we recommend the Vicks ComfortFlex, which stands out in speed and style. The average measurement time of eight seconds was the fastest among stick thermometers we tested, and customer reviews for the ComfortFlex consistently mention the speed as a key feature. During our tests, the backlit, large display was by far the easiest of those on the stick thermometers to read and interpret: One Wirecutter colleague chose this thermometer without hesitation because, he said, “I can actually see the numbers.” Plus, it comes with a useful, color-coded fever alarm and has a waterproof design.

Many of the thermometers we’ve tested have small numbers in a display window roughly 0.75 by 0.2 inches. The ComfortFlex features numbers twice the size of the next largest display, and it’s the only thermometer in our test group with a backlight feature—a must-have for anyone who shuns the light when sick or anyone who is taking a child’s temperature in the dark.

The ComfortFlex also has a useful fever alarm. Most of the thermometers we’ve tested boast alarms that change the number or tone of beeps when a temperature is elevated—a feature that is completely useless unless you memorize the “normal” beep structure in advance. The Vicks thermometer, on the other hand, color-codes the results, turning green for a normal temperature, yellow to indicate a slightly elevated temperature (above 99 °F), and red to alert you to a temperature greater than 101 °F. (Note that a fever in children over 6 months old is defined as starting at 99 °F for oral temperature and 100.4 °F for rectal temperature, which are both in the alarm’s yellow zone.) No preternatural ability to interpret shrill beeping required.

The Vicks ComfortFlex stores the most recent reading. The thermometer comes with a one-piece case and five single-use probe covers. Because these covers are meant to be trashed after one use, they won’t last you very long. You can buy replacements, but the thermometer itself is water resistant, so save your money—an alcohol swab or soap and water on the tip between each use will work just fine.

Flaws but not dealbreakers

When a temperature is ready to be read, the Vicks ComfortFlex emits an annoying, repetitive alert that you can’t silence. Although this is the case with every thermometer we’ve tested, the beep of the Vicks model is particularly grating.

Our version of the Vicks thermometer was Fahrenheit only. For us this was a flaw, but it would almost certainly be a dealbreaker for people who use Celsius. For years, Kaz Incorporated, the maker of this thermometer, has told us that newer versions will allow you to switch between the two scales, but as of 2021 this update has not yet happened.

Many of the negative customer reviews are complaints about the battery either arriving dead or dying after a few uses. The 3-volt, CR1225 battery is easily replaceable, but when you buy a new item, it should work—if yours is a dud, send it back.

Our pick: Equate Infrared In-Ear Digital Thermometer

The Equate Infrared In-Ear Digital Thermometer, one of our top picks for the best thermometers for kids and adults.

If you prefer an in-ear thermometer, or if the price of our forehead picks is too high, the Equate Infrared In-Ear Digital Thermometer is a great option. We found its large, backlit screen easy to read, and consecutive measurements remained the same in dozens of tests. It’s also fast, with temperature readings available within three seconds. As on our stick pick, the backlight changes color from green to yellow to red depending on the temperature measured, a feature we found helpful.

Unlike our stick thermometer pick, the Equate stores 10 temperature measurements (as opposed to just one) and can present readings in Fahrenheit or Celsius. Its audible fever alarm sounds if the detected temperature exceeds 99.5 °F.

A close-up of the digital display on the Equate In-Ear Thermometer.

The thermometer comes with a storage case and a handful of optional, disposable protective caps, which we found did not negatively impact the consistency or reliability of the measurements. You can buy additional protective caps.

The Equate is not waterproof, but you can wipe it down with a cloth dampened with 70% ethyl alcohol, following that with a dry cloth.

It takes two AA batteries and comes with a satisfaction-guaranteed promise of either a replacement or money back; according to an Equate customer service rep, that promise has no time limit.

If this model is unavailable when you’re shopping, we recommend the Kinsa Smart Ear Thermometer as a backup option. Although it is a smart thermometer, it’s perfectly functional even you never use the accompanying app.

Flaws but not dealbreakers

The Equate has no silent mode, and the manufacturer says that for maximum accuracy this thermometer should not be used on someone who is asleep. (We could not get official clarification as to why.) We also found this model difficult to fit into its storage case, and the disposable protective covers felt a bit flimsy.

Our pick: Hetaida htd8813c (available under multiple brand names)

Three similar infrared thermometers from Mobi, iProven, and Homedics.

In our tests, consecutive temperatures were consistent, and when we took readings in the exact same position, they rarely varied. This thermometer almost always recorded either the exact same temperature as the trusty ThermoWorks Wand No Touch Forehead Thermometer or came within two-tenths of a degree. (If the Hetaida htd8813c is unavailable, we recommend the ThermoWorks Wand as an alternative.)

Three similar infrared thermometers from Mobi, iProven, and Homedics, shown next to their packaging.

It also has a nice feature in that you don’t have to press a power button to turn it on: You just point, click, and get a reading in a few seconds.

The large and easy-to-read display remains backlit for a useful five seconds after you take a reading (in contrast to the ThermoWorks Wand’s two) and can show readings in both Fahrenheit and Celsius. This model also doubles as a surface thermometer, and you can mute the sound, too. When the sound is on, the beeps are loud and clear.

It comes with both audible and visible fever alarms that you can adjust: The default setting is to emit a sound and to display red if the detected temperature exceeds 99.2 °F, but you can toggle that number up and down in the thermometer’s settings.

This thermometer does not come with a case, and it looks and feels a bit cheap, which makes sense considering that in non-pandemic times it usually retailed for around $20 (in contrast to prices as high as $100 for the same thermometer over the past year). Depending on the retailer you purchase this model from, it may have poorly placed stickers on each side, as we found on the iProven version.

According to the manuals accompanying two of the three htd8813c versions we tried, this thermometer has a life expectancy of three years. You can clean it only by wiping it down with a soft, clean cloth.

It takes two AAA batteries. The Homedics and iProven versions come with one-year warranties. The Mobi model is covered by a 90-day warranty.

Also great: ThermoWorks Wand No Touch Forehead Thermometer

Our also great pick, the ThermoWorks Wand No Touch Forehead Thermometer.

It features a big, easy-to-read display (that stays backlit for a few seconds less than the screens on our other contactless picks do), and like our other contactless picks, it can double as a surface or object thermometer. Similarly, it can switch from Fahrenheit to Celsius, and you can use it with the volume turned on or off. The thermometer comes with an audible fever alarm that sounds if the detected temperature exceeds 99.5 °F, though you can mute that sound.

A close-up of the digital display on the ThermoWorks Wand No Touch Forehead Thermometer.

The Wand takes about two seconds longer to deliver readings, and stores half as many temperature readings, as the Hetaida htd8813c models do (25 versus 50). When it is not muted, the sound is very low and hard to hear (the Hetaida models’ sound is louder and clearer). After you take a reading, the screen remains backlit for only two seconds, which makes temperature reading in the dark more difficult. A particularly annoying series of four beeps chirps if you try to take another temperature too quickly, so if you’re used to taking consecutive readings without pause, you’ll likely need to get accustomed to the mandatory two-second wait between attempts.

In our 2020 and 2021 testing, the Wand produced consistently reliable readings, either matching our picks’ or coming within two-tenths of a degree. And like two of the three Hetaida htd8813c models we recommend, it is covered by a one-year warranty.

The Wand runs on two AAA batteries. According to a company spokesperson, it has a battery-life expectancy of around four years.

The Wand is not waterproof, but you can wipe it down with a cloth dampened with 70% ethyl alcohol and then with a dry cloth. It does not come with a storage case.

Other good fever thermometers

If the Vicks ComfortFlex is unavailable, we recommend the iProven DTR-1221A as a runner-up. Like the ComfortFlex, this traditional stick thermometer is speedy, reliable, and designed with a flexible probe. But unlike our pick, the DTR-1221A does not have a backlit display and is generally more difficult to read. Although the ComfortFlex was sold out for nearly all of 2020, it’s now reliably back in stock and generally priced less than the DTR-1221A.

If the ThermoWorks Wand No Touch Forehead Thermometer is your first choice but is unavailable, consider the company’s Wand Blue No Touch Bluetooth Forehead Thermometer. It’s the same contactless forehead thermometer but with the addition of smart capabilities, including wireless syncing with an app called ThermoWorks Health (iOS, Android). The Wand Blue is perfectly functional even if you don’t ever use the smart functions, though if you do use them, know that if you wish to store information—chiefly, temperature logs for multiple people—via the app, the company says: “ThermoWorks Apps do not collect any personally identifiable information, but in common with many commercial apps uses a third-party analytics service to collect anonymous usage information for the purpose of product improvement.” However, ThermoWorks does offer the option not to store data (this choice is embedded into the app sign-in). The terms of service and privacy policy lack the clarity we’d like to see, though the app itself does not offer much more than an extended text note would in the way of features, save for automated temperature tracking.

We previously recommended the Kinsa Smart Ear Thermometer, which is still a fine choice if you want an in-ear thermometer with smart capabilities, including wireless syncing with an app. Although many customer reviews allege inconsistency, in our tests we found this model to work fine with or without its smart capabilities. This thermometer’s accompanying app (iOS, Android) can automatically log temperatures for multiple people, among other features. Kinsa shares anonymized data in aggregate with public health experts, pharmacies, schools, and other third parties (including advertisers). It also publishes anonymized data in aggregate to HealthWeather. According to Kinsa’s privacy policy, the company says it “will never … [s]ell personally identifiable or individual data without the individual’s explicit permission.” Note that the first time you sync the thermometer to the Kinsa app, you have to enable location services. You can disable that as soon as you’re connected and still send temperature data from the thermometer to your phone.

The Kinsa QuickCare is a reliable stick thermometer with smart capabilities. Like the company’s Smart Ear, this model displays temperature readings directly on the device, which is handy if your phone is not nearby or you don’t wish to use the app after you’ve completed the setup process. The QuickCare syncs to the same iOS- and Android-compatible Kinsa app described above.

The competition

We previously recommended the DMT-489, and long-term testers who purchased that model in previous years have found that it remains a consistent, reliable ear-and-forehead thermometer. But in our 2020 testing, it varied too much from read to read in comparison with our newer picks.

In previous rounds of testing, we tried several other models and made the following determinations:

The Braun ThermoScan 5 ear thermometer requires lens caps for use (literally requires—the device will not operate until one is snugly in place). In a setting where someone might need to use the device on multiple people with no time or resources to clean it between uses, this thermometer is an excellent option. For at-home use, though, the need to keep an added component on hand makes it unappealing.

We liked that the Exergen TAT-2000C forehead model could be silenced, but the process was complicated and required some careful reading of the instruction manual. It also had a small, hard-to-read backlit display and was less intuitive to use than the Braun (for example, you need to press the main button 10 times to turn the alarm on and off). In addition, it runs on an (included) 9-volt battery—we generally try to avoid devices with batteries that we can’t replace by raiding the remote. Customer reviews suggest that this thermometer is not reliable over long periods of use.

We considered and quickly dismissed thermometer patches (such as the Fever Smart and TempTraq), which you apply to a person’s skin to continuously and remotely monitor their temperature. Such models are either many times the price of our picks or single-use, and—unless your doctor tells you otherwise—they’re overkill for most people.

Thermometers are selling for hundreds of dollars on Amazon as the online retailer tries to curb price-gouging during the coronavirus pandemic.

One listing for a non-contact infrared thermometer was selling for over $500 on Amazon at the time of publishing. Other listings were charging over $100 or $200. A similar non-contact thermometer was selling for around $60 on CVS' website. 

amazon thermometer price gouging

Amazon told Business Insider in a statement that "there is no place for price gouging on Amazon. We are disappointed that bad actors are attempting to artificially raise prices on basic need products during a global health crisis and, in line with our long-standing policy, have recently blocked or removed hundreds of thousands of offers."

In a statement to customers on its website, Amazon said that it is "working to ensure that no one artificially raises prices on basic need products during this pandemic."

Amazon said earlier this month that it has removed over 530,000 items and 2,500 sellers from its platform for price-gouging. The company also said it is assisting state attorneys general in prosecuting extreme cases of price-gouging. 

A Tennessee man who hoarded over 17,000 bottles of hand sanitizer before being blocked from selling them recently donated the supplies after Tennessee's attorney general investigated him for price-gouging, according to a report for The New York Times.

Best Infrared Thermometers On Amazon Reviews 2021 - Best Budget Infrared Thermometers (Buying Guide)

The best infrared thermometers in 2021

The best infrared thermometers allow you to take a temperature without touching the object, or person, in question. Now, when disease is prevalent and hygiene crucial, there are obvious advantages – you can quickly test a whole group of people without constant cleaning. It’s a lot less personal and invasive than  traditional approaches to taking a temperature.

The benefits of an infrared thermometer are not just limited to the medical context. A non-contact thermometer (or pyrometer) can easily measure a huge range of temperatures; ones you certainty don’t want to touch, from industrial freezers, though cooking pots, kilns, or running engines. 

Moreover, by avoiding contact, you eliminate influencing the measurement (no heat exchange) or transferring dirt and germs if, for example, you were testing food before serving. But do note that thermometers designed for industrial use have a much, much wider temperature measurement range - so are not suitable for medical use, where accuracy is critical.

An infrared thermometer works  a bit like a single-pixel infrared camera, measuring infrared radiation from an object. Like cameras, there are a variety of features and prices, suited to different applications (if you want more pixels, check out our guide to the best thermal imaging cameras.)

We've split our guide up into to sections, looking at the best infrared thermometers for measuring body temperature first, before moving onto more specialists industrial non-contact thermometers.

Best infrared thermometers for medical use

1. iHealth PT-3 Forehead Thermometer

Best infrared thermometer for simplicity


Time to reading: 1 sec

Accurate Range: 15℃-42.9℃ (59℉-104℉)

Accuracy margin: +/- 0.4˚C (0.3˚C in medical range)

Distance: 3cm/1-inch max

Reasons to buy

+Ambient sensors boost accuracy+Easy to use+Gorgeous design

Reasons to avoid

-Need to get quite close to the person

An elegant and popular choice, with a single button for a read out. Directed at the centre of the forehead from about 2cm (just under an inch), you can get an accurate reading and – unlike many more industrial designs – without a disturbing confirmation beep which, in practice, just annoys (or wakes) your kids. In a market swamped with just-good-enough packaging, it’s nice to find a quality document reminding you how best to use this kind of thermometer – specifically to measure the centre of the forehead, just above the nose, when dry. Sweat, even from a good cry, alters the texture of the skin which affects the measurement. The system algorithmically combines data from 100 readings plus a distance measure and an ambient temperature thermometer – all of which boosts confidence in the reading. Powered by 2xAAA batteries (included).

2. iHealth PT-2L Non-Contact Thermometer

Best infrared thermometer for simplicity


Time to reading: 1 sec

Accurate Range: 15℃-42.9℃ (59℉-104℉)

Accuracy margin: +/- 0.4˚C (0.3˚C in medical range)

Distance: 3cm/1-inch max

Reasons to buy

+Ambient sensors boost accuracy+Easy to use+Elegant design

Reasons to avoid

-Need to get quite close to the person

While the iHealth PT3 undoubtedly claims the points for styling with its subtle digital display, it is often one you’ll find yourself parting with a few extra dollars for. If iHealth’s technology (including the handy option of a silent mode) appeals but you want to get the best possible value then look at the very similar PT-2L model. The principle difference is that the readout appears in bluey-white on a black LCD display, which some users might even find clearer to read. The same method is used on both devices (over 100 readings taken in a second and averaged automatically) before a result is delivered. If you’re not sure what counts as a fever, just check for a smiling or sad face below the temperature on the display. Having only one button means that pressing and holding it enters Fahrenheit/Celsius switching mode, which may surprise some, but is at least simple. Batteries included. 

3. Withings Thermo

Best smart thermometer with app support


Time to reading: 0.5 sec

Accurate Range: 35.5-42˚C (95.9-107.6˚F)

Accuracy margin: +/- 0.2˚C (Medical)

Distance: 1cm (0.4in)

Reasons to buy

+Brilliant software+Swipe-to-touch display

Reasons to avoid

-You need to get close to the subject

A Bluetooth and Wi-Fi connected smart thermometer, the Withings Thermo doesn't just take accurate readings from the arteries in the forehead, it records them too. Ideal, of course, for children who don’t enjoy oral, in-ear, underarm, or rectal measurements. The 20 x 5 pixel LED display looks futuristic, and it doesn’t just show the read out – swipe up to select the family member. Encouragingly this product has actually proven itself for a few years and, the app is still current (despite past worries about Nokia’s management of Withings). There is a memory on-board for up to 32 readings, which can be transferred to an Android or iOS device (and, thanks to the wi-fi, distance is less of an issue than with Bluetooth-only devices). Oddly the app is limited to 8 profiles, but that’s enough for most families, and the real advantage of this system is the ability to record measurements to pass on to health professionals. US citizens might also be pleased to know they can offset the high cost via FSA health plans without prescription.

4. Comper Smart Forehead Thermometer

Great medical thermometer for families


Time to reading: 1 sec

Accurate Range: 35.5-42˚C (95.9-107.6˚F)

Accuracy margin: +/- 0.4˚F, +/- 0.2˚C (Medical)

Distance: 1-2cm (0.4-1in)

Reasons to buy

+Links up with smartphone via app +One-button operation

Reasons to avoid

-Android app has some user complaints-No object mode

Very similar in concept and design to the Withings Thermo, but this successful Kickstarter product claims it can support limitless profiles, but the app tops out at eight. Where that’s enough, it does present the data well, and can take offline readings later via bluetooth.  You can use this as a contact thermometer on the forehead, or can take a temperature from within an inch if you want to avoid touching your patient (though there seems to be up to a degree’s variance in the result). Powered by a pair of AAA batteries, the Comper claims a standby time of just over two years – or enough power for 600 measurements. At just 5 inches long, it is pretty portable too. It is worth noting, however, that the app asks you to share your phone number with developers, which seems somewhat unnecessary, 

5. Extech IR200 non-contact forehead thermometer

Best non-contact thermometer for schools & offices


Time to reading: 0.5 sec

Accurate Range: 2.0 to 42.5°C (89.6-108.5˚F)

Accuracy margin: +/- 0.5˚F, +/- 0.3˚C (Medical)

Distance: 5 to 15cm (1.9-Inch to 5.9-Inch)

Reasons to buy

+Simple, pistol-type control+Fast readings+Measures from up to 15cm away from subject+32-reading memory

Reasons to avoid

-Bulky for the home user

This is a great infrared thermometer for measuring the temperature of groups of people - such as students or colleagues. The pistol-like design means that it is easy to use - and with a measuring range of up to 5.9in away, five times that on most pistol-grip thermometers, there is greatly reduced risk of actually touching the person's forehead or transmitting infections. It has big button controls, and a simple-to-read display - and promises accurate readings in just 0.5 seconds. Extech is a subsidiary of FLIR - which is the biggest name in thermal imaging - which should give some reassurance as to the quality of this product. 

6. Braun Thermoscan 7

Best in-ear infrared thermometer


Time to reading: 1 sec

Accurate Range: 35.5 - 42˚C (95.9 - 107.6˚F)

Accuracy margin: +/- 0.15˚C (Medical)

Distance: 3cm/1-inch max

Reasons to buy

+Accurate readings+Easy-to-use fever warning 

Reasons to avoid

-Disposable probe guards need  replacing

While a forehead thermometer seems to embody the true ‘contactless’ dream of IR thermometers, there is much to be said for the in-ear measuring technique. This still uses IR measuring technology, but by pressing the probe into the ear using a disposable plastic guard you can push the accuracy to +/- 0.15˚C. There are 21 probe guards in the box, and 50 compatible ones cost about the same as a large latte (or rather more if you want Braun own-brand ones). 

This thermometer also uses Braun’s “Age Precision” technology to remind you what is a ‘safe’ temperature – tap the button to cycle through ‘0-3 months’ ‘3-36 months’ and ‘over 36 months’ and, when you take a reading, you’ll get a color-coded backlight (green for OK, yellow for ‘elevated’ or ‘red’ for high. It might sound silly, but especially with young kids it’s helpful to be reminded of when to worry and when not to! 

7. iProven DMT-978

Pistol-grip forehead thermometer


Time to reading: 1 sec

Accurate Range: 35.5 - 42˚C (95.9 - 107.6˚F)

Accuracy margin: +/- 0.5˚C

Distance: 5cm/2-inch max

Reasons to buy

+Easy to make forehead measurement+Colored screen fever warning

Reasons to avoid

-Like all laser thermometers, the lens needs cleaning

After giving the thermometer just a few moments to acclimatize to the room – something it’ll do automatically – all that is required is to ‘point and shoot’ at the surface you want to measure, ideally the middle of the forehead for a person. The system also has 50 memories, so could be used in a classroom scenario, and sports a backlight which changes color to warn of high body temperature, as well as LCD smiles at the bottom of the screen. Simple but effective and easy to grip.

8. Infrared Wall-Mounted Forehead Thermometer

Best infrared thermometer for small businesses & schools


Time to reading: 0.5 sec

Accurate Range: -32 to 43˚C (-89.6 to 109.4˚F)

Accuracy margin: +/- 0.2˚C

Distance: 5-10cm (2-4in)

Reasons to buy

+Great for small offices, shops and food outlets+Better range than a handheld+Big display

Reasons to avoid

-Not designed for portability-Optional 18650 battery not included

For cafes, stores and offices preparing to accept staff and visitors during heightened Covid-19 restrictions or a full lockdown, a wall-mounted digital thermometer is an ideal solution, meaning all can be directed to take their own temperature with a polite sign, rather than be forced to queue for a team member with a handheld ‘gun’. While normal temperatures are met with a green light, there is a ‘fever alarm’ with beep beep sound and red light, which might seem a little unsubtle, depending on the ambiance, but otherwise operation is relatively painless – it can be connected to a USB-C lead to power it, and this will also provide enough charge for up to a week depending. Wall mounting is as simple as hanging on a nail or hook, though you might wish to take a little more care to prevent theft. The only real downside is choosing the right hanging height, especially if some of your visitors are children.

Best infrared thermometers for industrial use

9. BTMeter BT-1500

Best infrared thermometer for high temperatures


Time to reading: 0.25 sec

Accurate Range: -50˚C to 1500˚C (-56˚F to 2,738˚F)

Accuracy margin: +/- 2%

Distance spot ratio: 30:1

Reasons to buy

+Great for industrial applications+Huge temperature range+Accurate at distance

Reasons to avoid

-Not suitable for body temperature readings

The wide temperature range of this thermometer gun makes it suitable for an almost immeasurable number of applications, from checking the surface temperature of a pizza in the oven through automotive to HVAC (though not accurate enough for use on humans). The dual laser beams help target the right spot and the fact the narrow 30:1 beam means you can get a reading at a safe distance even in a furness or kiln. All customers will be happy to find a case and battery included. Professionals will also appreciate the Emissivity adjustment; the reflective properties of different materials affect IR thermometers, but experienced pros will find the ‘E’ toggle easy to use, as well as appreciating the ability to set max and minimum warnings. The LCD is adequate, too, though contrast could be better. 

10. AstroAI 550

Simple, cheap but effective pistol-grip ABS IR thermometer


Time to reading: 0.5 sec

Accurate Range: -50 to 550˚C (-58 to 1022˚F)

Accuracy margin: +/- 2˚C(+/- 2%)

Distance spot ratio: 12:1

Reasons to buy

+Accessibly priced+Useful tool for mechanics and engineers+Laser pointer

Reasons to avoid

-Not suitable for body temperature readings

Ideal for use in electrical troubleshooting, HVAC, automotive and cooking and baking, this is a handy IR thermometer which still boasts some of the features of pricier rivals. You can take a continuous reading by holding the ‘trigger,’ or release to lock the result on screen, and the IR pointer will always make it easy to see where you’re getting your reading from. The Emissivity is fixed at 0.95, and of course the accuracy is certainly not medical grade, but as long as you work with that understanding you’ll still be able to, for example, check the surface temperature to cook the perfect steak, or locate problems areas with your home’s insulation that, once fixed, could save you more than the price of entry in heating bills! The 9V battery is given a good life thanks to the 7-second auto shutdown.

11. Wintact WT323C

Multipurpose IR thermometer ideal for detective work


Time to reading: 0.5 sec

Accurate Range: -50 to 650˚C (-58 to 1202˚F)

Accuracy margin: +/- 2˚C(+/- 2%)

Distance spot ratio: 12:1

Reasons to buy

+Built in UV light to reveal stains+Useful tool for mechanics and engineers+Laser pointer

Reasons to avoid

-Not suitable for body temperature readings

This tool starts from the same basics as many other trigger-grip handheld thermometers, but adds some functions to extend practicality. For one thing there is a K-type thermocouple socket for use with vehicular applications (and included probe). Secondly there is a UV flashlight of the kind seen in the more disgusting crime scene investigation dramas; what use you have in mind for this feature is your own, of course, but it could help you locate spots which need checking for temperature, or it might just help the paranoid check questionable furnishing in rented accommodation. Finally BBQ chefs will be pleased to note that there is an adjustable emissivity pyrometer function
