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...

States of Matter There are five states or phases of matter. The three most common states found on earth are solid, liquid and gas. The two less common states of matter occur at opposite ends of the temperature scale. The low-temperature state is the Bose-Einstein...

Williamson Short-Wavelength Advantage Infrared pyrometers rely on making a reading based on the amount of energy collected. The amount of energy collected can be affected by emissivity variance and optical obstructions. Selecting the shortest possible wavelength helps...
