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.

Infrared thermometer possesses the following features:
1. Positioning laser
2. Celsius / Fahrenheit temperature unit conversion
3. K-type thermocouple
4. Data retention
5. Low battery indicator
6. Environmental humidity measurement
7. Dew point temperature measurement
8. Surface temperature measurement
