How does a laser measure temperature?
IT DOESN’T!!! The laser is there to assist you in aiming the IRT to the surface area to see where you are acurally taking the temperature.The laser is offset from the Temp Gun’s infrared sensor by one half inch. The laser runs PARALLEL to the center of the sensor. This means that from 3 inches away, the laser is one half inch from the center of the temperature measurement. From 20 feet away, the laser is STILL one half inch from the center of the temperature measurement.
