When Buying an Infrared Thermometer Factors to Consider

Reading reviews of laser thermometers seems very technical and complicated. It is difficult to determine what you should consider before deciding on the best IR thermometer for you. Here are a few reasons to take note.

Temperature Range

Consider how much temperature range you need for your non-contact infrared thermometer. For example, suppose you plan to use your laser thermometer purely around the house to measure the grill’s temperature or the surface of your air conditioning unit.

In that case, you will not need a wide range of temperatures. However, if you intend to use your infrared thermometer when working in machinery, motorized engines, or any industrial setting, higher temperature ranges may be more relevant.


Accuracy of measurement with an infrared thermometer is essential, especially when working with expensive equipment or in a commercial kitchen where accuracy is highest.

For example, you need a specific and accurate reading every time you use a digital infrared thermometer in food safety applications. The more precise your model’s glasses are, the better your results will be.


EMCVT is the ability of a surface to emit heat radiation. Infrared thermometers with a fixed AMCVT setting of 0.99 are designed to take readings of highly structured surfaces, which means that the body will efficiently radiate an object’s temperature.

This is fine if you take on dark matte surfaces like asphalt, walls or tiles. Static MCVT settings will cause problems when measuring reflected surfaces with low distance ratings; for example, polishing metal measurements will result in false text when MCVT settings are not adjusted.

An IR thermometer gun that features adjustable MCCVT settings (between 0.10 and 1.00) will make you more accurate because you can calibrate the thermometer for each surface measurement.

Distance To Spot Ratio

The distance from the spot (DS) ratio refers to the measurable surface area that the infrared laser thermometer will read compared to the distance it needs to be read. For example, an Infrared thermometer with a 12: 1 D: S ratio will measure a field about 1-inch in diameter when it is 12 inches away.

As you measure the surface area of the surface farther away from the target, this will affect the reader’s accuracy if you need to calculate a smaller space. For example, suppose you want a 12: 1 D: S ratio model to measure an area of 1 meter to 2 inches.

In that case, you will not get accurate results because the thermometer will also measure the predetermined outside temperature. The area you are trying to measure. The D: S ratio lets you know what the ideal distance is for taking a proper lesson.

Your Budget

Think about how often you use your infrared laser thermometer and for what purpose. The best Infrared thermometer for your needs may not be the most expensive. Before deciding on your purchase, consider which features will give you the added value.

What Are Infrared Thermometers Used For?

Infrared thermometers can be used to measure the surface temperature of objects in industries and applications such as:

Automotive: Mechanics and automotive enthusiasts can use digital infrared thermometers to solve the problem of overheating, checking the usual spots of many components, including brakes, tires, radiators and engine time.

HVAC— Heating and cooling professionals use infrared thermometers to perform equipment checks and detection, drainage, insulation problems, faulty coils and other heat-related HVAC problems.

Electrical systems and circuit boards: IR thermometers can be used when working with electronic systems to check for hot spots, diagnose potential problems, and prevent equipment failure.

Cooking: An infrared thermometer gun lets you check the exact temperature of your grill or stovetop before placing it on top of that sweet short rib.

Manufacturing: In industrial and manufacturing applications, infrared thermometers are used to monitor products for quality assurance and schedule repairs and regularly monitor equipment temperature to prevent breakage of expensive equipment.

Food safety: Chefs and food service managers in commercial kitchens use infrared thermometers for continuous monitoring of food to ensure that the temperature is in line with food safety standards.

Medical— For measuring the body temperature of humans and animals.

Home use— There are many uses of IR temperature guns around the home, such as:

  • Testing for poor insulation and heating and cooling problems
  • Working in vehicles
  • Cooking on the grill
  • Making beer
  • Making soap and many more hobby or home improvement work

How to Use an Infrared Thermometer

Turn on your infrared thermometer gun. Select whether you like to record your measurements in Fahrenheit or Celsius. Read the manual to make sure you are familiar with the D: S ratio of your device. This will give better accuracy when taking measurements.

As a usual rule of thumb, the closer you get to a surface, the more precise the measurement. However, keep in mind that it may not be safe to be too close to an extremely hot object. If your IR thermometer gun is MCCVT compatible, go ahead and change the ambassador to the optimal setting for the level you are trying to measure.

With the laser’s direction, point your IR thermometer to the object you want to measure and pull the trigger to see the temperature on display. Try to choose a place on your surface that is not too close to other things at many different temperatures.

Do not use your IR thermometer to measure highly reflective or glossy surface items without adjusting for MCCVT. Don’t try to use your IR thermometer to measure things behind smoke or glass because the thermometer will measure smoke or glass temperature instead.


What Is an Infrared Thermometer?

Infrared thermometers are temperature sensitive instruments used to measure the non-contact of surface temperature. They work by estimating the temperature based on the thermal radiation that is emitted by a particular object.

The apparent temperature can be estimated by knowing the magnitude of the object and the amount of infrared energy emitted. Since they are non-communicative, they employ lasers to detect the thermometer, which is why they are sometimes called laser thermometers.

These are commonly used in industrial applications that require quick and accurate temperature readings far beyond the surface’s reach when the object’s temperature is not found too close or no probe can be inserted when the item is measured.

Q: How Does an Infrared Thermometer Work?

An infrared thermometer uses a lens to focus on the light coming from an object in the form of an infrared ray and it works by funneling a detector known as a thermopile. The thermopile inside the IR thermometer absorbs IR radiation and converts it into heat, converted into electricity.

The value of electricity is measured and then displayed on the screen of the thermometer. IR thermometers can measure multiple temperatures from the bottom frozen to the final high temperature. The range of available temperature measurements depends on each specific product.

For example, our best recommendation, the Fluke 62 MAX Plus, has a measurement area of -22°F to 1202°F (-30°C to 650°C) with an accuracy of ± 1°C or ± 1.0% of the reading from 0°C to 650°C. Usually, the more expensive infrared laser thermometers measure larger and have a greater distance to the spot ratio.

Q: How Accurate Are Infrared Thermometers?

Infrared thermometers are an accurate and convenient tool for rapid measurement of surface temperature. The precision specification of the IR thermometer depends on each model. Most infrared thermometers will have ± 2.0% measurement errors.

Two more factors need to be considered, which will determine the accuracy of the IR thermometer reading. These are the D: S ratio of the infrared thermometer and the ambiguity of the target.

Q: Can You Use an Infrared Thermometer for Cooking?

IR thermometers only measure the surface temperature, so they cannot accurately gauge your cooking food’s internal temperature. However, an infrared thermometer gun is useful for measuring the surface temperature of hot oil, a cast-iron skillet, a pan or your barbecue grill.

Just keep in mind when taking the temperature of a grill, the thermometer will factor in the visible surfaces’ weather with a sieve. To get a proper lesson, try placing a hard surface like an iron plate or skillet on the grill and let it preheat for 5-10 minutes.  Then spray the surface with some cooking oil for a proper release and proceed to take the temp.

Q: How Do You Calibrate an Infrared Thermometer?

It is essential to check the accuracy of any measuring instrument regularly to ensure your device is in good working order. A simple way to calibrate an infrared thermometer is to create a mixture of crushed ice and water in the bath. You want it to be a dirt consistency to make sure you measure a uniform temperature around 0 degrees Celsius as much as possible.

Then measure the mixture of ice and water to check the accuracy of your infrared thermometer. Another solution is to use comparable infrared cups. The comparative cup provides a solid matte black base with a high MCVT rating for an accurate reading. You can use the cup to equal the measurements from the infrared thermometer that holds.


A digital IR thermometer is a useful tool in any workshop, factory floor, commercial kitchen, or household because it can help you measure surface temperature quickly, accurately, and safely from a distance.

For professional use, the Fluke 62 Max+ is one of the best infrared thermometers because it has a wide range of measurements, 12: 1DS ratio, adjustable MCCVT settings and an accurate and robust all-rounder with dual lasers to help you pinpoint the edge of the measurement field.
