What is the Emissivity of XYZ?

Emissivity is a measure of the efficiency in which a surface emits thermal energy. It is defined as the fraction of energy being emitted relative to that emitted by a thermally black surface (a black body). A black body is … Continue reading

What is an Infrared Thermometer?

Infrared thermometers are non-contact thermometers. They measure the temperature of objects via their thermal radiation (typically infrared). Based on the amount of infrared energy being emitted by an object and its emissivity (see below), the object’s temperature can be determined. … Continue reading
