handheld industrial digital infrared thermometer temperature gun

Introduction This infrared thermometer is used for measuring the tem-perature of the object's surface, which is applicable for Va-rious hot,
hazardous or hard-toreach objects without contact safely and quickly.This unit consist of Optics, Temperature Sensor Signal amplifer,
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 amplfier and processing circuit. Specification
