General IRT205

1
INTRODUCTION
Thank you for purchasing General Tools & Instruments’
(General’s) IRT205 8:1 Infrared Thermometer. Using an optical
resolution (distance-to-spot ratio) of 8:1, the gun-style
instrument measures the surface temperature of a surface or
object from a distance by using an infrared (IR) sensor to
quantify its thermal radiation. This noncontact measurement
capability allows you to safely determine the temperature of
very hot or cold surfaces (from -4º to 536ºF/-20º to 280ºC),
inaccessible or hard-to-reach objects, and toxic substances.
A red laser pointer pinpoints the target area being measured.
Readings, in ºF or ºC, are displayed on a backlit LCD.
WHAT’S IN THE PACKAGE
The IRT205 comes on a blister-packed card with two “AAA”
Alkaline batteries in a cavity on the back.
PRODUCT OVERVIEW
Fig. 1 shows the key components of the IRT205. Fig. 2 shows all
