MODEL: GM550
Infrared thermometer
Instruction manual
Version: GM550-EN-00

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 to
reach objects without contact safely and quickly.
This unit consist of Optics, Temperature Sensor
Signal amplifier, Processing circuit and LCD
Display. The Optics collected the infrared energy
emitted 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 after the signal amplifier and
processing circuit.
Functions:
1. Celsius / Fahrenheit switchable
2. Equipped with a laser for aiming
3. Temperature hold
4. LCD backlight
5. 7 seconds auto power off
6. Light weight and easy operation
B. Warning & Cautions
1. Warning:
To avoid the potential situation may cause harm
or damage to people, please pay attention to the
following items:
1) Before you use this unit, check on the plastic
housing carefully. If there is any damage, do not
use it.
2) Do not point laser directly at eye or indirectly off
reflective surfaces.
3) Do not use this unit in the environment of
explosive gas, steam or dusty.

2. Caution:
To avoid the damage of the unit or the target,
please protect from the following situations:
1). EMF (electro-magnetic fields) from arc welders,
induction heaters.
2). Thermal shock (caused 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 attention 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 critical, make sure the
target is at least twice as large as the spot size.

D. Emissivity
Most 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, cover the target surface with masking
tape or flat black paint. Measure the tape or painted
surface when the tape or painted reach the same
temperature as the material underneath.
E. Operation
1. Operating the unit:
1). Open the battery door and
insert a 9V battery
properly.
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. Locating a Hot Spot:
To find a hot spot, aim the thermometer outside
of interest, then scan across with an up and down
motion until you locate the hot spot. (Figure 3)

G. Maintenance
1. Lens Cleaning:
Blow off loose particles using clean compressed
air. Gently brush remaining debris away with a
moist cotton swab. The swab may be moistened
with water.
2. Case cleaning: Clean the case with a damp
sponge/cloth and mild soap.
Note:
1) Do not use solvent to clean plastic lens.
2) Do not submerge the unit in water.
