Are you looking for the best infrared thermometer for adults? Then this review post is exactly what you need. We tested a range of infrared thermometer on the market and selected the top 5 to share with you.
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”. (source)
How accurate are infrared thermometers?
Infrared thermometers are extremely accurate when being used correctly. Not all materials give off thermal radiation in the same way, and a material’s ability to give off this type of energy is known as its emissivity. Emissivity is measured on a scale from 0.00 – 1.00.

When accounting for emissivity and being aware of the nearby object that might interfere with a temperature reading, you can rely on the accuracy of a non-contact thermometer’s temperature reading. Thermometers that feature adjustable emissivity rather than fixed emissivity, are the most accurate and dependable option.
This feature allows the user to adjust the emissivity to account for whatever type of material they are trying to measure the temperature of. You will be able to use an adjustable thermometer on just about any surface material and know that your reading is precise.
How infrared thermometers work?
Liquid thermometers, commonly containing mercury, provide a readout when the liquid expands in response to heat. An RTD digital thermometer contains a sensor that computes temperature change. What distinguishes the IR thermometer is that it focuses on infrared light at an object to detect and measure energy or radiation coming from its surface. The detector then translates the amount of electricity generated into a temperature reading.

How to Use an Infrared Thermometer
The process of obtaining an accurate measurement using an IR thermometer is simple, but proper usage is critical for obtaining the best results. For instance, where one points the thermometer matters. When measuring body temperature, the warmest part of the human body is actually located in the inside portion of the eye, and not on the forehead as many commonly believe. This is where you should point the thermometer. Fun fact: This is the most accurate location due to a vein that runs directly from the heart’s aorta to the inner corner of the eye. To safely take the temperature in the inner canthus, follow these steps:
- The patient should be steady and not moving around.
- The patient’s eyes should close while the physician lines up the laster.
- Physician turns off the laser.
- Patient reopens his or her eyes.
- Physician takes the temperature.
Remember that these steps will need to be modified for those who are visually impaired or deaf. Another consideration is that these instruments are meant to be used in close proximity. Reading the product guide to determine the ideal distance from the object is as important as the aim of the instrument.

Distance to spot ratio differs among each device and means that calculated positioning is required in order to gain an accurate reading of the target area. Too much area outside of the desired target will affect the accuracy of the reading. For reference, ICI’s infrared thermometer requires the person screening to stand between 5-15 centimeters away from the target.
