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. In units with a
laser, the laser is used for aiming purposes only.
Field of View
Make sure that the target is larger than the unit's spot
size. The smaller the target, the closer you should be to
