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 display 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 it. When accuracy is
critical, make sure the target is at least twice as large as the spot
size.
