A. Introduction
This infrared thermometer is used for measuring the temperature of an object's surface, applicable for various hot, hazardous, or hard-to-reach objects without contact, safely and quickly.
The unit consists of Optics, Temperature Sensor, Signal amplifier, Processing circuit, and LCD Display. The optics collect infrared energy emitted by the object and focus it onto the sensor. The sensor translates this energy into an electrical signal, which is then digitized and shown on the LCD after processing.
Functions:
- Celsius / Fahrenheit switchable
- Equipped with a laser for aiming ?
- Temperature hold
- LCD backlight
- 7 seconds auto power off
- Light weight and easy operation
B. Warning & Cautions
Warning:
To avoid potential situations that may cause harm or damage to people, please pay attention to the following:
- Before using this unit, check the plastic housing carefully. If there is any damage, do not use it.
- Do not point the laser directly at the eye or indirectly off reflective surfaces.
- Do not use this unit in environments with explosive gas, steam, or dust.
2. Caution:
To avoid damage to the unit or the target, please protect from the following situations:
- EMF (electro-magnetic fields) from arc welders or induction heaters.
- Thermal shock (caused by large or abrupt ambient temperature changes): allow 30 minutes for the unit to stabilize before use.
- Do not leave the unit on or near objects of high temperature.
C. Distance to Spot Size
When taking measurements, pay attention to the Distance to Spot Size (D:S). 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 this unit is 12:1.
This unit is equipped with a laser ?, which is used for aiming.
Diagram illustrating the relationship between the distance (D) from the object and the measurement spot size (S). At a distance of 300mm (12 inches), the spot size is 36mm (1.5 inches). At 900mm (36 inches), the spot size is 75mm (3 inches). At 1500mm (60 inches), the spot size is 132mm (5.3 inches). The diagram shows a cone of measurement, indicating that as distance increases, the measurement area (spot size) also increases.
2. Field of View:
Make sure the target is larger than the unit's spot size. The smaller the target, the closer the measurement distance. When accuracy is critical, ensure 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 may 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 once it reaches the same temperature as the material underneath.
E. Operation
1. Operating the unit:
- Open the battery door and insert a 9V battery properly. ?
- Pull the trigger to turn on the unit.
- Aim at the target surface and pull the trigger; the 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 the area of interest, then scan across with an up and down motion until you locate the hot spot. (Figure 3)

- (1) Trigger: When pulled, the LCD displays a reading with a SCAN icon. Releasing the trigger displays the reading with a HOLD icon for approximately 7 seconds. Features a built-in 7-second auto power-off function.
- (2) Laser on/off button ?
- (3) Celsius / Fahrenheit switch button (°C/°F)
- (4) Backlight on/off button: When the backlight is on, any operations will activate it for 7 seconds.
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:
- Do not use solvent to clean the plastic lens.
- Do not submerge the unit in water.
