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-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.
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
