How It Works - RayTek Raynger ST80 ProPlus Enhanced Manual

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 the temperature in less than a
second. You can safely measure surface
temperatures of hot, hazardous, mov-
ing, or hard-to-reach objects without
contact.

How it Works

Infrared thermometers measure the sur-
face temperature of an opaque object.
The unit' s optics sense emitted, reflect-
ed, and transmitted energy, which are
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.
