When surface temperatures need to be measured but are too hot or too difficult to read with traditional methods, a digital infrared thermometer is a popular solution. This laser guided, gun-like tool uses infrared technology to provide thermal readings quickly and accurately. It is simple to operate and performs an incredibly complex procedure inside a small casing.

A digital infrared thermometer has a pistol shape and usually is constructed of hard plastic with one or two lenses, similar to a small flashlight. Digital thermometers also have a small light-emitting diode (LED) reading area that displays the temperature. One of the most unique aspects of this tool is its guide that produces a small red laser point to help the user aim the thermometer with precision. Like firing a pistol, users pull a trigger and hold the red laser dot over the surface for a few seconds in order to get a reading.
