What is Emissivity? Does emissivity change with temperature? In order to answer this question, first we must understand emissivity. Emissivity is the ratio of the energy radiated from a materials surface to that radiated from a perfect emitter. A blackbody is an...

High-quality steel products require consistent process controls at every step. In order to accurately measure temperature, you must have a way to compensate for emissivity variation. The emissivity of steel varies depending on its surface character, which can vary at...
