Emissivity
Emissivity is a value between 0 and 1 that indicates an object's
ability to emit infrared energy. Emissivity is determined primarily
by the object's composition and surface finish. A polished, non-
oxidized metallic surface has an emissivity value near 0 and a
dull, black surface has an emissivity value near 1. (See
"Emissivity of Common Materials.")
The thermometer's sensitivity to emissivity is set at the factory to
0.95. If the emissivity of the object is not 0.95, the displayed
temperature could differ from the actual surface temperature. To
reduce this difference, apply black tape, black matte paint, or
black magic marker to the object if it is safe to do so and
measure the darkened surface.
