Non Contact Infrared Thermometer is utilized for the measurement of the temperature of the surface of object, applicable for varied hazardous, hot or hard to reach objects without contact quickly and safely. The Non Contact Infrared Thermometer is made using Temperature Sensor, Optics, Signal amplifier, LCD Display and Processing circuit. The Optics collected the infrared energy emitted by means of object and focus onto the sensor. Thereafter, the sensor translates the energy into an electric power signal. This signal will be turned out to be digital displayed on the LCD screen after the signal amplifier & processing circuit.
