DTM Series blackbody calibration source(radiation source) adopts a black body body and an integrated temperature control structure, and the working temperature range is 30℃～50℃. It can optionally communicate with a computer through RS232. High emissivity, good stability, small uncertainty and easy operation.

DTM Series blackbody radiation source 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 calibration source 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.

Main Features

1. Large diameter cavity, which can adapt to most D:S radiation thermometers;

2. Imported 0.1-level temperature control meter is selected, and the temperature control accuracy is high;

3. The temperature control meter has a multi-point correction function;

4. Comply with the regulations of JJG 856-2015 "Radiation Thermometer for Work".
