How to use a handheld infrared thermometer?

The infrared thermometer is used for measuring the surface temperature of the object. ATO infrared thermometer is non-contact, handheld and easy to use, especially suitable for measuring the temperature of various hot, hazardous or hard-to-reach objects. This infrared thermometer consists of Optics, temperature sensors, signal amplifier, processing circuit and LCD display. The Optics collects the infrared energy emitted by the object and focus it to the sensor. Then the sensor transforms the energy into an electricity signal. The signal will be turned into a digital number shown on the LCD after the signal amplifier and processing circuit.
