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 consists of Optics, Temperature Sensor Signal amplifier, Processing circuit and LCD Display. The optics collect the infrared energy emitted by the object and focus onto the Sensor. Then the sensor translates the energy into an electricity signal. This signal will turn out to be a digital shown on the LCD after the signal amplifier and processing circuit.
Distance to spot size:
- When taking 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 measuring distance. When accuracy is critical, make sure the target 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 (preset in the unit). Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate for this, adjust the units emissivity reading or cover the surface to be measured 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.
