Page 6: How It Works
How it Works Infrared thermometers measure the surface temperature of an object. The unit’s optics sense emitted, reflected, and transmitted energy, which is collected and focused onto a detector. The unit’s electronics translate the information into a temperature reading which is displayed on the unit. The laser is used for aiming purposes only. -
