Ayucat: /* External links */ fmt (link title) {{unreferenced|date=December 2008}} '''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... - ayucat
