Best Non Contact Thermometers Reviews (Updated 2020)
Non-contact thermometers, also known as infrared (IR) thermometers, measure temperature from a distance. Every form of matter with a temperature above absolute zero (0 K) emits infrared radiation relative to its temperature. This is called characteristic radiation. The emissivity of a material is the relative ability of its surface to emit energy by radiation. By knowing the amount of infrared energy emitted by the object and its emissivity, the object’s temperature can be determined most of the time. IR thermometers infer temperature by measuring the amplitude of IR energy being emitted from the surface.
Recent innovations have reduced the production cost and increased the reliability of these non-contact thermometers, opening the doors to many new applications. Four primary factors—application, instrument accuracy, reliability and budget—help determine which type of non-contact temperature measurement instrument should be used.
The most common infrared thermometer types are spot infrared thermometers, infrared scanning systems and infrared thermal imaging. The last two of these are more complex and costly than spot infrared thermometers and are mainly used in quality monitoring of manufacturing processes.(source)
How Do Forehead Thermometers Work?
The best non contact forehead thermometer contains a small lens that emits an infrared beam which bounces off the object and back to a detector which absorbs any radiation. This radiation is turned into heat and then into electricity. The thermometer can then convert this electricity into an accurate temperature reading.
The way forehead thermometer for adults work may sound complex but they basically detect a difference between the unit and the object that’s targeted. The way the electronics work allows the thermometers to give quick and accurate reading.

Although it is possible to get a thermometer which displays one of another, most modern devices allow you to switch between Celsius and Fahrenheit when showing degrees. This can usually be adjusted during setup and can meet the user to whichever standard of measurement they use.
One major advantage to owning a digital thermometer is the ability to read it in the dark if you’re taking the temperature of a sleeping child. The display of a thermometer usually has a backlight for reading in the dark and is displayed in digital format so it’s easy to read. Some can also flash on and off to indicate a fever or other warnings that might be relevant.
Most forehead thermometers come with sounds in the device, usually to indicate when it’s ready to check the temperature or to show once the temperature has been read. Although they can be convenient, they can also be a bother as they might wake a sleeping child, so look for one with a silent mode option if possible.
