Infrared thermometer calibrating and testing rack

The utility model discloses an infrared thermometer calibrating and testing rack which is mainly used for testing and calibrating small-size handheld infrared thermometers. The infrared thermometer calibrating and testing rack comprises a calibrator platform (1), a distance scale (21) and an instrument stand (3), wherein the calibrator platform (1) is fixed on a straight rail (2), the distance scale (21) is arranged on the rail (2), and the instrument stand (3) can slide on the rail (2). Thermometers can be arranged on the infrared thermometer calibrating and testing rack at set distance. In the whole calibrating process, the infrared thermometer calibrating and testing rack measures the temperature of the same range of a radiation source at one position all the time, can reduce measurement error caused by uneven temperature of the target surface of the radiation source, and also can conduct linear analysis of the temperature measurement error of the thermometers.
