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.
