Emissivity
The emissivity of a material is its
efficiency in emitting thermal energy.
Non-reflective surfaces have a higher
emissivity (closer to 1) than reflective
surfaces (closer to O). Inaccurate results
may occur when measuring reflective
surfaces such as glass, polished wood,
and granite.
To take accurate temperature
measurement of reflective surfaces with
low emissivity, place a strip of masking
tape over the surface and allow for it to
