Introduction
We are confident you will find many uses for your
handheld noncontact thermometer. Compact, rugged,
and easy to use—just aim, press the trigger, and read
surface temperatures in less than a second. You can
safely measure surface temperatures of hot, hazardous,
or hard-to-reach objects without contact.

How it Works

Infrared thermometers measure the surface tempera-
ture of an object. The unit' s optics sense emitted (E),
reflected (R), and transmitted (T) 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.
