How to Calibrate Infrared Thermometer
1. On the black body radiation source, use a second-class or higher standard thermocouple, a photoelectric pyrometer, or an infrared thermometer with a higher accuracy level than the infrared thermometer to be calibrated as a standard, and then adjust.
2. All objects whose temperature is higher than absolute zero are constantly emitting infrared radiation energy to the surrounding space. The size of the infrared radiation energy of an object and its distribution according to the wavelength have a very close relationship with its surface temperature.
Therefore, by measuring the infrared energy radiated by the object itself, its surface temperature can be accurately determined, which is the objective basis for infrared radiation temperature measurement.
