Best Infrared Thermometers – Types and Buying Guide

Best Infrared Thermometers/An infrared thermometer is a thermometer that infers temperature from a portion of the thermal radiation sometimes called black-body radiation emitted by the object being measured. They are sometimes called laser thermometers as a laser is used to help aim the thermometer, or non-contact thermometers or temperature guns, to describe the device’s ability to measure temperature from a distance. By knowing the amount of infrared energy emitted by the object and its emissivity, the object’s temperature can often be determined within a certain range of its actual temperature. Infrared thermometers are a subset of devices known as thermal radiation thermometers.

When you are cooking a dish, the temperature control is the most important skill to cook the dish perfectly. If you do not know the temperature of the dish you are preparing at any given time, there are chances of overcooking or undercooking. With the advancement of the technology and electronic gadgets, you can measure the temperature without even contacting the surface of the object you want the temperature of. This is achieved by using the best-infrared thermometer. Not just cooking, it is useful in various constructional and mechanical works where the temperature is the most crucial thing.

Specifications and Features of Infrared Thermometers

As with most instruments, infrared thermometers are available in a range of styles with specifications suited to one’s budget and needs. Some of the most common specifications and features include:

  • Emissivity – Emissivity refers to the ability of a material to emit thermal radiation. All materials absorb, reflect and emit radiant energy. Certain materials, however, are better at doing this than other materials. Emissivity, therefore, is the ratio of the radiation emitted by a surface of a material to the radiation emitted by a blackbody, both a perfect absorber and emitter of energy, at the same temperature. All radiation absorbed by a blackbody will also be emitted by it. Blackbodies, therefore, have an emissivity of 1.0. Dark materials with a rough surface generally have a high emissivity. Asphalt, for example, has an emissivity of 0.90 meaning that it absorbs and emits 90 percent of radiant thermal energy and reflects only 10 percent.
  • Distance-to-spot ratio – The distance to spot ratio, usually abbreviated as D:S, refers to the size of the measurement area (spot) when the device is held at a certain distance from the target. For instance, a unit with a 20:1 D:S ratio will produce a 1” diameter measuring spot when held 20” from the target, or 2” spot when held 40” away. This is important since the spot is an area over which temperatures are averaged. If the actual target is very small, it is best to have a unit with a higher ratio so as not to risk inaccurate measurements by including areas not targeted in the measurement. Calculating the spot size using the D:S ratio may be misleading for close focus units or those involving long distances
  • Spectral range – Infrared light consists of wavelengths from 0.7 to 1000 μm. Spectral range refers to the specific range of wavelengths captured by an infrared thermometer. Most infrared thermometers operate under 20 μm. This is due to both cost efficiency as well as the negative effects on accuracy caused by the atmosphere on longer wavelengths.
  • Laser sight – Laser sights are often found on infrared thermometers. Their only function is to help aim the unit. The actual measurement area is larger than the red dot.
  • Fixed vs handheld – Most imagers are handheld, making them ideal for spot-checking temperatures for maintenance, troubleshooting, or inspection. Some, however, are designed to be fix mounted as part of a process application. There is a wide range of outputs available to integrate into a control system.

How To Use Infrared Thermometers?

To give a better understanding, I have embedded a video on how to use infrared thermometers from Home Inspection Estate Inc. YouTube Channel. Please note that everything you read or watch here is intended to give more information only and not professional advice. Always seek professional help to avoid any danger from improper usage.

Applications for Infrared Thermometers

Infrared thermometers are highly versatile making them indispensable tools in the technician’s toolbox. They can be employed anywhere at any time. Some common applications include:

  • Checking mechanical equipment for hot spots that may be a sign of impending failure
  • Inspecting electrical panels, circuit breakers, and outlets for hot spots
  • Checking heater or oven temperature, for calibration and control purposes
  • Detecting hot spots / performing diagnostics in electrical circuit board manufacturing
  • Checking for hot spots in firefighting situations
  • Monitoring materials in the process of heating and cooling, for research and development or manufacturing quality control situations
  • Identifying hot/cool spots during the home inspection to find drafts or to determine if insulation is adequate
  • Checking temperatures as part of auto maintenance


The accuracy of the handheld IR thermometer is primarily determined by the distance-to-spot ratio (D/S Ratio). This ratio is the size of the area being evaluated by the IR thermometer as it relates to distance. In other words, the area being measured becomes larger as the distance increases. The smaller the target, the closer you should be to it. This ratio will have a significant impact on the accuracy or precision of the reading. If the target you are measuring is six inches in size, and your handheld infrared thermometer has a D/S ratio of eight to one, then the maximum distance at which you can reliably measure the temperature of the target is 48 inches (8:1 x 6 = 48). Beyond this distance, not only is the target being measured but whatever else falls within the “spot” is being measured as well. This means that if a very hot object is the target, and it is in cooler surroundings, then measurements taken beyond the maximum distance will include cooler elements, lowering the “average” of what is in the “spot.”

As the target size decreases or the distance to the target increases, a larger D/S ratio becomes necessary. Using the same example and changing first the target size and then the D/S ratio, you see that this formula helps you decide the correct D/S ratio and, subsequently, the handheld IR thermometer for your needs:

  • D/S Ratio x Target Size or 8:1 x 2 = maximum measure distance of 16 inches
  • D/S Ratio x Target Size or 12:1 x 2 = maximum measure distance of 24 inches

D/S ratios vary greatly, so carefully compare this feature of handheld IR thermometers when shopping. The two biggest factors to consider when selecting an IR thermometer are the D/S ratio and temperature range.


It is unimaginable that you can measure the temperature of any object accurately without even touching the object with the gadget for measurement. Starting from food to various hazardous objects, an infrared thermometer is a must-have for every house and worker. All the infrared thermometers listed here are of top-notch quality with exclusive features to give you the best value for your money with which you make the purchase of your favorite infrared thermometer.
