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.
