Emissivity

Emissivity describes the energy-emitting characteristics

of materials. Most organic materials and painted or

oxidized surfaces have an emissivity of about 0.95. If

possible, to compensate for inaccurate readings that

may result from measuring shiny metal surfaces, cover

the surface to be measured with masking tape or flat

black paint (<150°C / 302°F ) and use the high emissivity

setting. Allow time for the tape or paint to reach the

same temperatures as the surface beneath it. Measure

the temperature of the tape or painted surface.

1. Changes of surrounding ambient temperature

can result in inaccurate reading, allow time for

the instrument to adopt the change of ambient

before use. Specified accuracy applies after 30

minutes when the instrument changes to a different

environment ambient.
