INFRARED THERMOMETER
A. INTRODUCTION
This infrared thermometer is used for measuring the
temperature of the object’s surface, which is applicable
for various hot, hazardous or hard-toreach objects
without contact safely and quickly.
This unit consist of Opcs, Temperature Sensor Signal
amplier, Processing circuit and LCD Display. The
Opcs collected the infrared energy emied by object
and focus onto the Sensor. Then the sensor translates
the energy into an electricity signal. This signal will be
turned out to be digital shown on the LCD aer the
signal amplier and processing circuit.
B. WARNING & CAUTIONS
1.Warning:
To avoid the potenal situaon may cause harm or damage to people, please pay aenon to the following
items:
1) Do not point laser directly at eye or indirectly o reecve surfaces.
2) The unit cannot measure through transparent surfaces such as glass or plasc. It will measure the surface
temperature of these materials instead.
3) Steam, dust, smoke, or other parcles can prevent accurate measurement by obstrucng by the units opcs.
2. Cauons:
Infrared thermometer should be protected for the following:
1 ) EMF (electro-magnec elds) from arc welders, inducon heaters.
2) Thermal shock (cause by large or abrupt ambient temperature changes allow 30 minutes for unit to stabilize
before use).
3) Do not leave the unit on or near objects of high temperature.
C. DISTANCE TO SPOT SIZE
1. When take measurement, pay aenon to the Distance
to Spot Size. As the Distance (D) from the target surface
increases, the spot size (S) of the area measured by the unit
becomes larger.
The Distance to Spot size of the unit is 12:1.
This unit is equipped with a laser, which is used for aiming.
2. Field of view:
Make sure the target is larger than the unit’s spot size.
The smaller the target the closer measure distance. When
accuracy is crical, make sure the target is at least twice as
large as the spot size.

D. EMISSIVITY
Emissivity: Most organic materials and
painted or oxidized surfaces have an
emissivity of 0.95(preset in the unit).
Inaccurate readings will result from
measuring shiny or polished metal
surfaces. To compensate for this, adjust
the units emissivity reading or cover the
surface to be measured with masking
tape or at black paint. Measure the
tape or painted surface when the tape
or painted reach the same temperature
as the material underneath.
E. OPERATION
1. Operang the unit:
1 ) Open the baery door and insert the baery.
2) Pull the trigger to turn on the unit;
3) Aim at the target surface and pull the trigger, then temperature will be shown on the LCD.
This unit is equipped with a laser, which is only used for aiming.
2. Locang a Hot Spot:
To nd a hot spot, aim the thermometer outside of interest, then scan
across with an up and down moon unl you locate the hot spot.
