INTRODUCTION

The IRT3 is a small and lightweight non-contact thermometer
that measures the surface temperature of an object from a
distance by using an IR sensor to measure its thermal
radiation. A laser pointer indicates the target area (spot)
whose temperature is being measured.

SAFETY INSTRUCTIONS

The IRT3’s targeting laser is a Class 2 type that emits less
than 1mW of power at a wavelength of 655nm. Avoid direct
eye contact with laser light radiation. U.S. law prohibits
pointing a laser beam at aircraft; doing so is punishable by
a fine of up to $10,000 and imprisonment.

WHAT’S IN THE BLISTER PACK

The IRT3 comes in a plastic blister pack with two
pre-installed batteries and this user’s manual.
