Emissivity
All objects emit invisible infrared energy. This ability,
called emissivity, is based upon the material that the
object is made of and its surface finish. Emissivity
values typically range from 0.10 for a very reflective
object to 0.98 for a near perfect black body. The probe
senses this energy assuming that the target has an
emissivity value of 0.95. This value is factory set in the
probe. If the actual target emissivity is less than 0.95,
the indicated temperature could be less than the actual
target surface temperature. To correct for this, apply
masking tape or a coat of matte paint to the target. The
resulting target will have an emissivity of approximately
0.95.
