What is an Infrared Thermometer

How to measure the temperature of a moving object? How to know whether your frying pan is hot enough for roasting a steak? How to detect a duct leakage? These simple tasks were rather difficult in the past, yet they are very simple today thanks to infrared thermometers (also called laser thermometers). These devices measure the temperature without contacting the object. Non-contact thermometers are applied in many spheres - from construction to medicine. These devices are also quite helpful in household use: for example, you can measure the temperature of the metal surface after polishing it (we recommend picking the right polisher). We have selected the most advanced IR thermometers available on the market, so read this brief review and take your pick!

If you work in residential or industrial construction, you certainly should use a reliable and accurate moisture meter.

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 a household use; you can use them to detect a draught 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 you need to take into account is the distance-to-spot ratio every laser thermometer has. This ratio means the size of the spot on the object compared to the distance to it. If you need to measure the temperature at a small distance, you can opt for a device with a small ratio. And vice versa, the father 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. 

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 rubberizied grip.

Comparison of Non-contact Laser Infrared Thermometers

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.
