INTRODUCTION
Thank you for purchase of the IR Thermometer. This is
capable of non-contact (infrared) temperature
measurements at the touch of a button. The built-in laser
pointer increases target accuracy while the backlight LCD
and handy push-buttons combine for convenient, ergonomic
operation.
The Non-contact Infrared Thermometers can be used to
measure the temperature of objects’ surface that is improper
to be measured by traditional (contact) thermometer (such
as moving object, the surface with electricity current or the
objects which are uneasy to be touched.)
Proper use and care of this meter will provide years of
reliable service.
FEATURES:
zRapid detection function
zPrecise non-contact measurements
zDual laser sighting
zUnique flat surface, modern housing design
zAutomatic Data Hold
z℃/℉switch
zEmissivity Digitally adjustable from 0.10 to 1.0

zMAX temperature displays
zBacklight LCD display
zAutomatic selection range and Display Resolution 0.1º
C(0.1ºF)
zTrigger lock
zSet high and low alarms
WIDE RANGE APPLICATION:
Food preparation, Safety and Fire inspectors, Plastic
molding, Asphalt, Marine and Screen printing, measure ink
and Dryer temperature, HVAC/R, Diesel and Fleet
maintenance.
SAFETY
zUse extreme caution when the laser beam is turned on.
zDo not let the beam enter your eye, another person’s
eye or the eye of an animal.
zBe careful no to let the beam on a reflective surface
strike your eye.
zDo not allow the laser light beam impinge on any gas
which can explode.

Distance & Spot Size
As the distance (D) from the object increases, the spot size
(S) of the area measured by the unit becomes larger. The
relationship between distance and spot size for each unit is
listed below. The focal point for each unit is 914mm (36”).
The spot sizes indicate 90% encircled energy.

Note:
zField of View: Make sure that the target is larger than
the unit’s spot size. The smaller the target, the closer
you should be to it. When accuracy is critical, make
sure the target is at least twice as large as the spot
size.
