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.
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.
