material's ability to emit radiation. Many organic materials and surfaces have an
emissivity of about 0.95. Metallic surfaces or shiny materials have a lower emissivity.
More accurate readings can be obtained by masking the measurement point with black
paint or tape. Measurements cannot be taken through transparent surfaces such as
glass. Instead, the surface temperature of the glass surface is measured.
