Operation theory Infrared thermometer temperature meter gun probe measurement is use thermopile sensor to receive the radiation infrared signal of the object, then the sensor got the signal through the optical system to focus on the measured object, then convert the received electronic signal to measure the wave length, then convert to electric signal through the LCD display showed the temperature to the end user.
