WebWhat is Emissivity? Emissivity is a measure of a material’s ability to emit infrared energy. It is measured on a scale from just about 0.00 to just below 1.00. Generally, the closer a material’s emissivity rating is to 1.00, the more that material tends to absorb reflected or ambient infrared energy and emit only its own infrared radiation.
