Reminders
1. Not recommended for use in measuring shiny or polished metal
surfaces ( stainless steel, aluminum, etc.). See Emissivity
2. The unit cannot measure through transparent surfaces such as
glass. It will measure the surface temperature of the glass instead
3. Steam, dust, smoke, etc. can prevent accurate measurement by
obstructing the unit’s optics

Emissivity
Emissivity is a term used to describe the energy-emitting characteristics
of materials.
Most (90% of typical applications) organic materials and painted or oxi-
dized surfaces have an emissivity of 0.95 (pre-set in the unit). Inaccurate
readings will result from measuring shiny or polished metal surfaces. To
compensate, cove the surface to be measured with masking tape or flat
black paint. Allow time for the tape to reach the same temperature as the
material underneath it. Measure the temperature of the tape or painted
surface.
