The 5 Best Infrared Thermometers in 2023 Tested and Reviewed

Carefully graded and selected by our reviewers to be the best in terms of performance, design, and usability, you’ll be able to see which models are the best infrared thermometers here!

Thirteen best infrared thermometers in 2023 arranged in a line-up on a wooden countertop, against a blurry kitchen background.

Any well-stocked kitchen should have a good thermometer on standby in a cupboard somewhere. With an IR thermometer, you can immediately learn the temperature of nearly any object simply by pointing the thermometer at its surface and pressing the trigger. These non-contact thermometers make your temperature estimations on everything from stovetops to BBQ grills much safer and easier.

What’s the Use of an Infrared Thermometer in a Kitchen?

IR thermometers exploit a fascinating physics phenomenon.

Everything around us, including our own bodies, emits thermal radiation generated by the object's heat. The intensity of thermal radiation corresponds to the object's temperature, meaning that hotter objects emit stronger or "brighter" thermal radiation.

Appliances and household objects typically emit this radiation as infrared (IR) light. Infrared wavelength is invisible to the naked eye but detectable with specialized equipment like an IR thermometer. The device translates the intensity of that radiation as a temperature reading!

An IR thermometer is an essential tool for your kitchen. It lets you measure the surface temperatures of stovetops, ovens, grills, and other appliances without direct contact. This makes it safer to use than other kinds of best kitchen thermometers that we’ve covered..

Note that infrared thermometers won’t be able to measure the internal temperature of food, like meat. For that, check out the best meat thermometers.

How We Tested Infrared Thermometers

We put each thermometer through a testing battery consisting of three major sections, and each portion has different weightings in the final score: Performance (70%), Design (20%), and Usability (10%).

Performance (70%)

In the performance section, we conducted two small tests to evaluate the thermometers.

The first test, known as the cold test, involved ice. We filled an insulated box with icy water and waited until the temperature stabilized at 32°F. To ensure accuracy, we used a temperature probe to measure this temperature. Once the water hit the proper temperature, we took IR-thermometer temperature readings at two distances: 12 inches and 16 inches from the surface.

We then compared these readings to the temperature of the ice. The scores were based on how closely the IR thermometer was to that actual value of 32°F.

The second test (the hot test) called for cooking oil. Following a similar methodology, we heated a pan of cooking oil on a stovetop and maintained a temperature of 321°F. We took two measurements—one at 12 inches and one at 16 inches from the oil—and compared them to the oil's actual temperature (321°F). The closer the thermometer's readings were to the oil's temperature, the better the performance score.

The cold test with ice accounts for 40% of the overall performance evaluation, while the hot test carries a weight of 60%.

To calculate the performance score for each model, we take the score obtained in each section and divide it by the respective weighting. Then those two numbers can be averaged.

Design (20%)

In the design section, we look at the overall build quality and the solidness of its construction. From the battery compartment’s lid to the display panel to the laser emitter, our reviewer examines every detail to ensure that the thermometer is likely to last a long time.

The quality of certain details like the handle and the display panel, tie into the usability section, too.

Usability (10%)

Speaking of usability, this section has to do with the user experience. We seek to answer questions about how comfortable the thermometer feels in the hand and how easy it is to use. We also look into how functional the thermometer is by investigating its additional features and measurement modes.

  • The display panel is dim

We had a tough time deciding on our third-place pick. This Helect thermometer ranked just below Eventek and Wintact IR thermometers in terms of measurement accuracy, but it was significantly less friendly when it came to usability. The Helect has no extra measurement modes, so it's less versatile than many others.

Still, ultimately, we decided to award the thermometer the third place anyway because of its great measurement accuracy.

The Helect IR thermometer achieved reasonable scores in the performance tests. It scored 7.45 in the cold test and 8.45 in the hot test. Our hot test is weighted higher, giving the Helect a performance score of 8 out of 10—equal to the Wintact WT530.

Despite being an average product with a budget feel, it has a solid build quality, weighs 5.73 ounces, and features a 1.25-inch backlit LCD screen. The laser emitter’s single dot is bright enough to do the job.

While it serves its purpose within its price range, the Helect thermometer’s limitations may render it unsuitable for some users. In particular, we deemed it only “passable” in terms of handling because the curved grip felt uncomfortable (especially for users with small hands). 

It also lacks extra measurement modes, which could be a drawback for those seeking more versatility.

Overall, the Helect IR thermometer exceeded our initial expectations in terms of performance, but it has drawbacks regarding design and usability. Pay attention to these aspects before you buy.

Factors to Consider

IR thermometers may seem pretty straightforward, but there’s a lot of complex physics under the hood.

Here are a few things we check with each thermometer.

Measurement accuracy

This is the most important part of our test: how accurately the thermometer can measure the temperature of a surface. Our testing methodology for IR thermometers contains two sections to evaluate the accuracy: a cold test using a chest filled with icy water and a hot test using hot cooking oil.

Temperature range and emissivity settings

For kitchen-grade thermometers, the range typically spans from -58°F to 1,122°F (-50°C to 600°C).

The thermometer will display an error message if the surface temperature falls outside of this range. You should select a model with a functional range that matches how you expect to use it.

One factor that affects what surfaces you can measure is emissivity. Emissivity refers to how surfaces emit IR energy, and it is expressed as a numerical value between 0 and 1.0.

A black-body object, which reflects no energy, has an emissivity of 1.0.

Many IR thermometers feature an option to adjust their emissivity settings. They give you more accurate results if you select the emissivity setting that closely approximates that of the object you’re measuring.

Models that don’t allow users to modify the emissivity setting are fixed at 0.95.

Distance-to-Spot Ratio

The Distance-to-Spot (D:S) ratio refers to the relationship between the distance from the sensor to the target and the diameter of the measurement area. A thermometer's claimed D:S ratio can help us determine how big its target must be when measured from a given distance. 

For example, if we say a thermometer has a D:S of 10:1, then the diameter of the area that it can measure is equal to around one-tenth the distance between the thermometer and the object. So, if you were to measure an object from 10 inches away, the sensor would collect thermal data from a target area 1 inch in diameter. 

Thermometers with higher D:S ratios can sense the temperature of smaller areas from greater distances.

Build quality

Since IR thermometers are industrial tools, they’re often built to last. Most are constructed from shockproof plastic that can withstand drops and impacts. A good IR thermometer shouldn’t need replacement for years.

Display and interface features

Every IR thermometer has a display panel on the back. This main interface will tell you the temperature readings and the current settings. 

The colored LCD panel of the Sovarcate HS980E IR thermometer. The screen currently reads 26.8°C.

Most models feature black-and-white LCD panels. Some even include a backlight that can be toggled on and off for use in dark conditions. 

However, there are also premium thermometers on the market that boast color LCD panels. One such example is the Sovarcate HS980E.

Another noteworthy feature is the laser emitter. It's important to note that the laser itself doesn't measure the object's temperature. It’s there to show you exactly where the IR sensor is pointing. 

While most models have a single-dot laser emitter, a few project more unique patterns. For instance, the Mecurate IR thermometer sports a 13-point laser emitter, with the outer dots forming a circle. This circle shows you the measurement area’s diameter.

Shown here is the unique 13-point laser pattern produced by the emitter of the Mecurate IR thermometer. The 12-dot outer circle makes it easier for the user to visualize the diameter of the measurement area, which roughly corresponds to the D:S ratio of the thermometer.


How to use an infrared thermometer?

Using infrared thermometers is incredibly simple. Just press and hold the trigger, aim the laser pointer at the point you wish to measure, and the temperature reading will instantly appear on the screen. Once you release the trigger, the thermometer will hold the last temperature reading on the screen for your convenience.

Some thermometer models allow you to switch between measurement modes to display the average, minimum, and maximum temperatures.

How accurate are infrared thermometers?

Accuracy differs from model to model. Most in our database claim to measure within ±2°F of the actual temperature. You’ll have to read your IR thermometer’s manual for more details.

What are some of the factors that affect an infrared thermometer’s accuracy?

Accuracy depends on many factors, some of which are outside of your control (at least with a standard consumer-grade IR thermometer).

Emissivity is one. Every surface and material has a different emissivity value. Lots of thermometers allow you to choose between several emissivity settings to better tune your sensor to the material you’re measuring. It’s not exact, but it gives you some measure of control. 

Distance is another factor. The acceptable sensing distance will depend upon your device’s D:S ratio. 

Most unpredictable are environmental factors. Ambient temperature, humidity, and air currents around the object will all impact the measurement accuracy. You can try to control these as much as possible, but it’s not always doable.

This is why you’ll rarely get perfect accuracy with any thermometer and why most IR thermometers have an “error tolerance.” A tolerance of ±2°F from the actual temperature is most common.

Can I use these thermometers to measure body temperature?

Thermometers designed for measuring body temperature belong to a different product class and have far higher precision.

As a result, IR thermometers intended for industrial or kitchen use explicitly state in their user manuals that they should not be used to measure body temperature.

What are the advantages of infrared thermometers compared to traditional thermometers (i.e., Mercury-in-glass thermometers)?

The greatest advantage of an infrared (IR) thermometer is its non-contact measurement ability. That means you can measure the surface temperature of your target without making physical contact with it.

Cheap IR thermometers can provide precise readings within a 1-inch spot from 12-16 inches away. This makes them invaluable in your kitchen, enabling you to effortlessly monitor the temperatures of your grill, stovetop, oven, and other appliances.

Can I use an infrared thermometer to measure liquids?

Yes, you can use an IR thermometer on liquids. However, keep in mind that it will only be able to measure the surface temperature of the liquid. It won’t be able to tell you the temperature at the bottom or center of the liquid body.
