Warning
(units with laser sighting)
Do not point laser directly at eye or indirectly off
reflective surfaces.
Cautions
All models should be protected from the following,
▲ EMF (electro-magnetic fields) from arc welders,
induction heaters
▲ Static electricity
▲ Thermal shock (caused by large or abrupt ambi-
ent temperature changes—allow 30 minutes for
unit to stabilize before use)
▲ Do not leave the unit on or near objects of high
temperature
Introduction
We are confident you will find many uses for your
handheld noncontact thermometer. Compact, rugged,
and easy to use—just aim, pull the trigger, and read
current 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. In units with a
laser, the laser is used for aiming purposes only.
