GM900 IR Thermometer
Introduction
This infrared thermometer is used for measuring the temperature of the object’s surface, which is applicable for
various hot, hazardous of hard-to-reach objects without contact safety 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.
