Infrared thermometers can be used to serve a wide variety of temperature monitoring functions. A few examples provided to this article include:
-
Detecting clouds for remote telescope operation
-
Checking mechanical equipment or electrical circuit breaker boxes or 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 fire fighting situations
-
Monitoring materials in process of heating and cooling, for research and development or manufacturing quality control situations

Infrared thermometers measure temperature using blackbody radiation (generally infrared) emitted from objects. They are sometimes called laser thermometers if a laser is used to help aim the thermometer, or non-contact thermometers 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 be determined.

The most basic design consists of a lens to focus the infrared energy on to a detector, which converts the energy to an electrical signal that can be displayed in units of temperature after being compensated for ambient temperature variation. This configuration facilitates temperature measurement from a distance without contact with the object to be measured. As such, the infrared thermometer is useful for measuring temperature under circumstances where thermocouples or other probe type sensors cannot be used or do not produce accurate data for a variety of reasons.
