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:
Rapid detection function
Precise non-contact measurements
Dual laser sighting
Unique flat surface, modern housing design
Automatic Data Hold
°C/°F switch
Emissivity Digitally adjustable from 0.10 to 1.0
MAX temperature displays

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
Use extreme caution when the laser beam is turned on.
Do not let the beam enter your eye, another person’s
eye or the eye of an animal.
Be careful no to let the beam on a reflective surface
strike your eye.
Do 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:
Field 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.

MEASUREMENT OPERATION
① Hold the meter by its Handle Grip and point it
toward the surface to be measured.
② Pull and hold the Trigger to turn the meter on and
begin testing. The display will light if the battery is
good. Replace the battery if the display does not
light.
③ Release the Trigger and the HOLD display icon will
12
appear on the LCD indicating that the reading is being
held. In HOLD status, press the UP button to turn on
or off the laser. And press the DOWN button to turn on
or off the backlight.
④ The meter will automatically power down after
approximately 7 seconds after the trigger is
released.(Unless the unit is locked on)
This device is provided with vision alarm function.
During measurement, if the measured temperature is
higher than the High Alarm temperature ( High Alarm is
ON ), red LED will flash on the LCD.
During measurement, if the measured temperature is
lower than the Low Alarm temperature ( Low Alarm is
ON ), red LED will flash on the LCD.
Note: Measurement considerations
Holding the meter by its handle, point the IR Sensor
toward the object whose temperature is to be measured.
The meter automatically compensates for temperature
deviations from ambient temperature. Keep in mind that
13
it will take up to 30 minutes to adjust to wide ambient
temperatures are to be measured followed by high
temperature measurements, some time (several
minutes) is required after the low (and before the high)
temperature measurements are made.
This is a result of the cooling process, which must take
place for the IR sensor.
5. BATTERY REPLACEMENT
① As battery power is not
sufficient, LCD will display
“ ” replacement with
one new battery type 9V is
required.
② Open battery cover, then
take out the battery from instrument and replace with a
new 9-Volt battery and place the battery cover back.

NOTES:
How it Works
Infrared thermometers measure the surface
temperature of an object. The unit’s optics sense
emitted, reflected, and transmitted energy, which is
collected and focused onto a detector. The unit’s
electronics translate the information into a temperature
reading, which is display on the unit. In units with a
laser, the laser is used for aiming purposes only.
Field 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.
Distance & Spot Size
As the distance (D) from the object increases, the spot
size (S) of the area measured by the unit becomes
larger. See: Fig: 1.
Locating a hot Spot
To find a hot spot aim the thermometer outside the area
of interest, then scan across with an up and down
motion until you locate hot spot.
Reminders
15
① Not recommended for use in measuring shiny or
polished metal surfaces ( stainless steel, aluminum,
etc.).See Emissivity
② The unit cannot measure through transparent surfaces
such as glass. It will measure the surface temperature
of the glass instead.
③ Steam, dust, smoke, etc., Can prevent accurate
measurement by obstructing the unit’s optics.
Emissivity
Emissivity is a term used to describe the
energy-emitting characteristics of materials.
Most (90% of typical applications) organic materials
and painted or oxidized surfaces have an emissivity of
0.95 (pre-set in the unit). Inaccurate readings will result
from measuring shiny or polished metal surfaces. To
compensate, cove the surface to be measured with
masking tape or flat black paint. Allow time for the tape
to reach the same temperature as the
materialunderneath it. Measure the temperature of the
tape or painted surface.
