7.2 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.
