Store Previous Readings

Taking a simple temperature measurement is rarely useful, as those who often need to use an infrared thermometer can tell you. Temperatures can change all of the time, and keeping track of these changes can be quite important. This device makes this task much easier thanks to its automatic data hold feature, which stores previous readings. This lets you easily find and analyze any variations in the temperatures, giving you the ability to do this analysis immediately after the readings or even sometime later, whenever you prefer.

The device itself is also quite easy to use, with an ergonomic form that makes it easy to hold and highly accurate with wherever you point it. The controls on the device are easy to recognize, with each button sporting a small image that gives you a clear indicator of what it is used for. Temperature readings are all displayed on the large backlit LCD display, letting you easily see the readings in any light conditions. The only gripe we really have here is that there is a slight delay between the time the measurement is taken and the reading appears on the screen, although this really isn't a big deal and shouldn't impact the usefulness of the device. All things considered, this is one of the best infrared thermometers that we have seen.

Comparison of Non-contact Laser Infrared Thermometers

What Is an Infrared Thermometer?

There are many situations where a regular thermometer can't be used, such as when you need to measure the temperature of moving objects, electrical circuits, mechanical equipment, and other things that cannot be touched by hand. While you could definitely resort to using some other methods of measuring the temperature of these surfaces, a more convenient and - more importantly - more accurate way would be to use an infrared (or laser) thermometer.

IR thermometers will come in handy not only when you work on mechanical equipment or vehicles but also anywhere else in your home for measuring temperature from a distance.

Using an infrared thermometer is as easy as anything. All you need to do is direct it at an object you're working on and the tool will do the trick. And if it has an auto shut-off feature as well, you will be able to use it with little to none supervision at all.

If you want to get yourself only the best infrared thermometer rather than waste money on cheap knock-offs, this review is tailored specially for you. We offer you the selection of the best-selling IR thermometers along with the key specs to consider before making a choice. We hope our guide will help point you in the right direction.

Best Infrared Thermometers

What Features to Compare

Temperature Range

There are several important features to consider when choosing a decent infrared thermometer. And the temperature range is among the most important ones since it determines the scope of application of the thermometer. The IR thermometers with a relatively narrow range are suitable for household use; you can use them to detect a draft or check how well the doors and windows are insulated. These temperature guns are also widely used in cooking. The laser thermometers with a wide temperature range are suitable for use by professionals; they are common at construction and industrial sites.

Distance-to-spot Ratio & Accuracy

The next important tech spec to consider is a distance-to-spot ratio. This ratio means the size of the spot on the object compared to the distance to it. If you mostly measure the temperature from small distances, you can opt for a device with a small ratio. And vice versa, the farther the object is, the higher the ratio a gun should have. As far as accuracy is concerned, if you need an infrared thermometer to use at worksites, opt for accurate non-contact thermometers.

Build Quality

Since infrared thermometers can be used in a wide variety of different work areas, having a model that is built for such use cases can be very important. Most people tend to not look too deeply into this, but if you're going to use the device in areas where there is always the risk of dropping the device or damaging it in some other way, then you will want to be sure that the device is made sturdy and durable enough to easily handle such uses cases. Some models are actually built to meet certain certification standards, so you might want to check whichever model you are looking at to see if this is the case with it.

Conveniences

Finally, consider whether the chosen thermometer is convenient to use. Some of the features just cannot go underestimated. Most IR thermometers, for example, can retain the maximum reading taken during measurements, so you can compare several readings further in use, knowing the highest temperature detected. Other thermometers feature a memory option, allowing you to check several readings taken during a different period of time. Also, we'd recommend you to consider what type of material the case of the gun is made of. This can be really important, especially if you work in quite dusty and humid environments. Opt for a dust-proof and water-resistant infrared thermometer with a rubberized grip.

FAQ:

Q: How does an infrared thermometer work?

A: Each infrared thermometer has a special sensor called a thermopile. This sensor detects infrared radiation reflected from an object, turns it into the heat which then transforms into electricity. The more electricity, the higher the temperature of the object is.

Q: What does ‘infrared’ mean?

A: Infrared radiation is a part of electromagnetic spectrum. This kind of radiation is, actually, the heat that our skin feels. Though infrared radiation is generally invisible, it might emit light at really high temperatures.

Q: What are infrared thermometers used for?

A: IR thermometers allow measuring a temperature of distant objects with the help of a special heat sensor. It means there is no need to contact the object; instead, just direct the laser beam onto it, and the device will show you the temperature. For example, laser thermometers are used to measure the temperature of air vent ducts, engines, machinery parts, and even kitchenware.

Q: The manual has a confusing spec called ‘distance-to-spot’ ratio. What does it mean?

A: In a nutshell, it means the size of the spot on the object being measured from a certain distance. For example, if a non-contact thermometer has a distance-to-spot ratio of 12:1, it means you will get a 1’’ wide spot at the distance of 12’’.

Q: What is the temperature range most IR thermometers support

A: Laser thermometers are used for a large scope of industrial and construction jobs, so most of them offer quite a wide range. The minimum temperature is usually around -60 degrees F, whereas the maximum amounts to around 1,600 degrees F.

Q: What does ‘emissivity’ mean?

A: Without going deep into technical details, emissivity is the ability of a certain material to emit infrared radiation. It’s measured from 0.00 to 1.00. The higher the emissivity of the material is, the more accurate the readings of the laser temperature gun will be. Most devices come with a useful table with the emissivity of different materials; you should use it to get accurate readings for low-emissivity materials (such as aluminum, for example).

Q: Can I use a laser thermometer to check the doneness of food?

A: No. IR thermometers can measure the surface temperature only. If you need to know the internal temperature of solid foods, a probe thermometer must be used.

Q: Is it necessary to calibrate non-contact thermometers?

A: Yes. The frequency of calibration is usually specified in manuals. As usual, laser temperature guns are sent back to manufacturer and put into calibration in appropriate conditions.

Q: How do I know when it’s time to calibrate an IR thermometer?

A: Most non-contact temperature guns perform a check-up of all functions when they are switched on. If calibration is required, an error message is displayed to a user.

Q: Can I use an IR thermometer to measure the temperature of baby formula?

A: Yes. However, you should stir it well before taking the measurement so that the formula has the same temperature as a bottle or a bowl. The same approach is applied to measuring water temperature in a baby bath.
