How To Calibrate Infrared Thermometer Gun. Check if the temperature reading on the infrared thermometer matches that of the conventional thermometer. Ir thermometer to check weld preheat is useless.
A good rule of thumb is to take multiple readings and base those measurements on the 10 times the ir thermometer response time. Read off the value of the temperature displayed by the thermocouple and adjust the temperature of the infrared temperature gun. To assure traceability, you need to calibrate your infrared thermometer on a regular basis.
Connect the thermometer to the pot and turn on.
Verifying infrared thermometer accuracy 741 e. Hold the dut thermometer in front of the 4180. Black bodies have an emissivity equal to 1, so set the infrared temperature gun to this value. Calibrate the device properly to ensure proper function and accurate measurements.
