Single hole and double hole blackbody constant temperature baths are used for temperature calibration of body temperature measuring instruments, with high accuracy and easy use.
Company Profile
Shanghai Fangrui Instrument Co., Ltd. is a manufacturer of measuring instruments (with a license for manufacturing measuring instruments such as electronic scales and moisture meters).
All kinds of instruments or devices produced by our company are self-developed and have independent intellectual property rights, ensuring that users can use them with confidence. All instruments produced can be sent for third-party verification by Shanghai Institute of Metrology and Testing Technology, with a one-year warranty and lifetime service.
The blackbody constant temperature bath adopts our company's self-developed AI artificial intelligence PID control method for high-precision temperature control instruments.Within the full range of temperature control, the linearity is very good. The DC series with a display accuracy of 0.1 has a temperature control accuracy error (the difference between the actual temperature in the tank measured by a standard thermometer and the set temperature) of less than 0.2 ℃; The HDC series with a precision of 0.01 has a measurement error of less than 0.04 ℃.


The panel has changed the usual practice, without a mechanical switch, and has a good waterproof effect. There is only one power switch on the back of the temperature control box for the entire constant temperature bath. Heating and cooling are both fully automated and require no human intervention. Higher work efficiency and more reliable use.

Characteristics of Blackbody:
1. Made of whole piece copper processing;
2. The conical surface has undergone anti-corrosion treatment (most of the products on the market do not have anti-corrosion treatment and are directly immersed in water. Over time, copper will also corrode)Corrosion, affecting normal use)
3. There is a handle on the panel for easy removal of the black body
Multiple protection functions:
1. It has a break protection function to prevent the instrument from losing control;
2. There is a liquid level protection device that can effectively prevent various faults caused by heating tube burnout;
3. The upper limit over temperature alarm function can be set by oneself. If it exceeds the range, it will immediately sound an alarm;
