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

it. When accuracy is critical, make sure the target is at

least twice as large as the spot size.

Distance & Spot Size

As the distance (D) from the object increases, the spot

size (S) of the area measured by the unit becomes
