③Steam, 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,

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.
