• Emissivity
Emissivity is a term used to describe the energy-emitting
characteristics of materials. The higher of this value
means the more capability of radiation emittance the
materials has. Most organic materials and painted or
oxidized surfaces have an emissivity of 0.98. Metal
surfaces or shiny materials has a lower emissivity and
give inaccurate readings. Please note this during
applications.
