Specification: The infrared temperature sensor calculates the temperature of the surface of the object by measuring the intensity of the infrared radiation emitted by the target without contacting the target. Non-contact temperature measurement is the biggest advantage of infrared thermometers. Users can easily measure the target temperature that is inconvenient to approach or move. Note: this item do not have the English Manual.
