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
safe 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.
D:S=12:1
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.

age to people, please pay attention to the following items:
1) . Do not point laser directly at eye or indirectly off reflec tive surfaces.
2) . The unit cannot measure through transparent surfaces
such as glass or plastic. It will measure the surface tem perature of these materials instead.
3) . Steam, dust, smoke, or other particles can prevent acc urate measurement by obstructing by the units optics.
2. Caut io ns:
Infra re d therm om eter sh ou ld b e pro te ct ed for th e

3). Do no t le ave the u ni t on or nea r ob je cts o f hi gh

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.

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 temp erature 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 1)
