3. Not recommended for use in measuring shiny or

polished metal surfaces (stainless steel, aluminum,

etc.). See Emissivity.

4. Steam, dust, smoke, etc., can prevent accurate

measurement by obstructing the unit‘s optics

Emissivity

Most 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.
