Product Usage Instructions
Warning & Cautions
- Before using the unit, carefully check the plastic housing for any damage. If there is damage, do not use the unit.
- Avoid pointing the laser directly at the eye or indirectly off reflective surfaces.
- Do not use the unit in environments with explosive gas, steam, or dust.
- Avoid exposing the unit to EMF (electro-magnetic fields) from arc welders and induction heaters.
- To avoid thermal shock, allow the unit to stabilize for 30 minutes before use when there are large or abrupt ambient temperature changes.
- Do not leave the unit on or near objects of high temperature.
Distance to Spot Size
When taking measurements, pay attention to the Distance to Spot Size ratio.
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.
Field of View
Make sure the target is larger than the unit’s spot size. The smaller the
target, the closer the measurement distance should be. When accuracy is
critical, ensure that the target is at least twice as large as the spot size.
Maintenance
- Lens Cleaning: Blow off loose particles using clean compressed air. Gently brush away remaining debris with a moist cotton swab. The swab may be moistened with water. Do not use solvents to clean the plastic lens. Do not submerge the unit in water.
- Case Cleaning: Clean the case with a damp sponge/cloth and mild soap.
Emissivity
Most organic materials and painted or oxidized surfaces have an emissivity
of 0.95, which is pre-set in the unit. Inaccurate readings may result from
measuring shiny or polished metal surfaces. To compensate, cover the target
surface with masking tape or flat black paint. Measure the temperature of the
tape or painted surface when it reaches the same temperature as the material
underneath.
Operation
- Open the battery door and insert two 1.5V AAA batteries properly.
- Pull the trigger to turn on the unit.
- Aim at the target surface and pull the trigger to display the temperature on the LCD. The laser is only used for aiming.

FAQ
-
Q: How do I clean the lens of the infrared thermometer?
A: Blow off loose particles using clean compressed air. Gently brush away remaining debris with a moist cotton swab. The swab may be moistened with water. Do not use solvents to clean the plastic lens. -
Q: How should I handle thermal shock when using the thermometer?
A: To avoid thermal shock, allow the unit to stabilize for 30 minutes before use when there are large or abrupt ambient temperature changes. -
Q: What should I do if I need to measure shiny or polished metal surfaces?
A: Shiny or polished metal surfaces may give inaccurate readings. To compensate, cover the target surface with masking tape or flat black paint. Measure the temperature of the tape or painted surface when it reaches the same temperature as the material underneath. -
Q: How long does the unit stay on before it automatically powers off?
A: The unit has a built-in 7-second auto power off function. If the trigger is not pulled within 7 seconds, the unit will turn off automatically.
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.
Warning & Caution
Warning: To avoid the potential situation may cause harm or damage to
people, please pay attention to the following items
- Before you use this unit, check on the plastic housing carefully. If there is any damage, do not use it.
- Do not point laser directly at eye or indirectly off reflective surfaces.
- Do not use this unit in the environment of explosive gas, steam or dusty.
Caution
To avoid the damage of the unit or the target, please protect from the
following situations:
- EMF (electro-magnetic fields) from arc welders and induction heaters.
- Thermal shock (caused by large or abrupt ambient temperature changes allow 30 minutes for unit to stabilize before use.
- Do not leave the unit on or near objects of high temperature
Distance to spot size
- 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
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
tar- get is at least twice as large as the spot size.

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.
Operation
Operating the unit
- Open the battery door and insert 2″1.5V AAA batteries properly.
- Pull the trigger to turn On the unit.
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.
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)
