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 independently developed and produced, and have obtained national invention patents (ZL 2014 1 0280162.5) and utility model patents (ZL 2012 2 0171247.6; ZL 2011 2 0065224.2). Having independent intellectual property rights ensures that users can use it with peace of mind in the long term. 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.

Circulating water bathHigh precision temperature control instrument using our company's self-developed AI artificial intelligence PID regulation method for constant temperature bath.

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 measurement error of HDC/PHDC series with 0.01 accuracy is less than 0.03 ℃.

Support the use of external sensors to control the thermostatic bath, which has the advantage of automatically adjusting based on the temperature of the external container.

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.

Three programs can be programmed, each with 20 program segments.

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;
Each series of circulating water baths can conduct constant temperature tests directly in the bath or utilize external circulation function to guide the controlled constant temperature liquid in the bath to other devices through hoses connected to other equipment.

Circulating water bathWidely applicable in fields such as biotechnology, medicine, food, chemical engineering, metallurgy, chemical analysis, petroleum, etc., it provides users with a high-precision, controlled, and temperature uniform constant field source. It is an ideal constant temperature device for research institutes, universities, factory laboratories, and quality inspection departments.

Main technical parameters of the 6-liter series circulating water bath:

Note: For temperatures below -40 ℃, it is an ultra-low temperature constant temperature bath. Detailed technical parameters are "ultra-low temperature constant temperature bath"
