• Reminders
1 The unit is not recommended for use in measuring shiny or polished metal surfaces (stainless
steel,.aluminum,.etc.).See.Emissivity.

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 oxidized 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, cover 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.
