Emissivity Selection

The correct emissivity value is important for you to make
the most accurate temperature measurements. Most
painted or oxidized surfaces have an emissivity of 0.93
(default value set in the Meter). This is correct for non-
contact temperature measurements on most bearing
housings.
Inaccurate measurements can result from shiny or
polished metal surfaces. To compensate, put masking
tape or flat black paint on the measurement surface. Make
sure that the tape is the same temperature as the
measurement surface before you make a measurement.
For other applications the Meter has additional preset
emissivity values:
Aluminum (e=0.30)
Iron (e=0.70)
Steel (e=0.80)
Paint (e=0.93) – default value

Wood (e=0.94)

1. Go to the Device Settings menu.
2. Push  and  to highlight Material Emissivity.
