Consequently, these products help to measure the temperature of inaccessible or moving objects without difficulties. Infrared thermometers basically consist of the following components: • lens • spectral filter • detector • electronics (amplifier/ linearization/ signal processing) thermoMETER LS... -
Page 60: Emissivity
A low emissivity (reflective surfaces) carries the risk of inaccurate measuring results by interfering infrared radiation emitted by background objects (flames, heating systems, chamottes). To minimize measuring errors in such cases, the handling should be performed very carefully and the unit should be protected against reflecting radiation sources. thermoMETER LS... -
Page 61: Determination Of Unknown Emissivity's
Adjust the emissivity of your infrared thermometer to 0,98 and take the temperature of the colored surface. Afterwards, determine the temperature of a directly adjacent area and modify the emissivity until the measured value corresponds to the temperature of the colored surface. thermoMETER LS... -
