DTM Series-Portable Blackbody Calibration Source(Infrared Calibrator) the main function is to generate standard radiation at a certain temperature, so it is mainly used to verify various radiation thermometers in temperature measurement, such as optical high humidity meter, infrared thermometer, infrared thermal imager Etc.,
Our company's DTM blackbody Calibrators are divided into two types: cavity and surface source. The temperature range covers low, medium and high temperature sections. Customers can choose two different electrical control methods: ordinary type and color touch screen according to their needs.
