DTM Double Cavity Series--Portable Blackbody Calibration Source is a small and cost-effective blackbody specially designed for human body temperature measurement applications and infrared NETD calibration and responsivity testing. It is specially used for real-time temperature relative drift correction of infrared body temperature rapid screening instrument, infrared thermal imaging temperature measurement alarm system and other products.

DTM Blackbody Calibration 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 Blackbody Calibration 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 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.

Features

1.DTM-20N500G Dual Cavity Black body Radiation Source contains two independent black body cavities and large diameter cavity, which can adapt to most D:S radiation thermometers;

2. This Dual Cavity Radiation Source Use 0.1-level imported temperature control meter, and the temperature control accuracy is high;

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

4. Wide temperature range, -20°C to 500°C;

5. With RS485 communication function, it is easy to be embedded in the system; it is light in weight and easy to carry.
