Emissivity
Most organic materials and painted or oxidized surfaces have an
emissivity of 0.95 (fixed setting in the model RHT70). Inaccurate
readings will result when measuring shiny or polished surfaces. To
compensate, cover the surface under test with masking tape or flat black
paint. Allow time for the tape to reach the same temperature as the
material underneath then measure the temperature of the tape or the
painted surface.
