8.2 Determination of unknown emissivity
► First determine the actual temperature of the measuring object with a thermocouple or contact sensor.
Second, measure the temperature with the infrared thermometer and modify the emissivity until the
displayed result corresponds to the actual temperature.
► If you monitor temperatures of up to 380 °C you may place a special plastic sticker (emissivity dots –
Part
No.:
ACLSED
) onto the measuring object, which covers it completely.

Set the emissivity to 0.95 and take the temperature of the sticker. Afterwards, determine the temperature
of the adjacent area on the measuring object and adjust the emissivity according to the value of the
temperature of the sticker.
