High temperature circulating baths are widely used in fields such as chemical engineering, petroleum, medicine, biology, physical chemistry, metrological control, and electronic instrument processing, and are commonly used as instruments in research institutes of major universities.

Technical features:
Dual use of water and oil: can choose temperature range from room temperature to 100 ℃, room temperature to 200 ℃, and room temperature to 300 ℃;
● External circulation function: The centrifugal jet circulation pump can draw out the constant temperature liquid in the tank, establish a second constant temperature field, and control the external experimental container of the machine.
Capacity range: 5L, 10L, 15L, 20L, 30L, 50L, 100L, and can also be designed and produced according to user requirements for non-standard products.
● Temperature control function: Equipped with the latest generation of integrated PID automatic temperature control program, with the highest precision PT100 temperature sensor AA level built-in. Equipped with a large screen high brightness LCD screen, displaying in both Chinese and English, with a digital resolution of 0.01 ℃, ensuring precise and stable temperature control.
Internal circulation function: Adopting a non heat centrifugal circulation pump to avoid the influence of traditional water pumps on the tank temperature field due to their own heat generation. The internal circulation system is designed based on the principle of porous U-shaped reflux circulation, achieving turbulent and highly uniform flow and temperature fields within the tank.
The body shell adopts mirror anti aging static spray painting technology, and the inner pot and tabletop are made of high-quality S304 brushed stainless steel panel.
The finely crafted front panel and tabletop of the chassis, coupled with a unique humanized R-rounded design structure, can prevent operators from being accidentally injured by sharp edges.
The drainage system can meet the needs of various laboratories and enterprises for liquid exchange during production.
● Safety protection device:
1. Equipped with power-off protection function
2. Equipped with upper and lower temperature alarm setting function
3. Low water level protection and alarm function
4. Temperature runaway protection and alarm function
5. The heating tube has low water level anti dry burning and explosion-proof functions
● Optional Function Guide
1. An optional extended external PT100 temperature sensor can be used to detect and control the temperature of the external system in real-time during external circulation.
2. Optional built-in temperature control program with 1-30 segments, capable of automatic program temperature control and real-time display of the set temperature time program running status.
3. Optional RS232 or RS485 communication interface, easy to connect to the upper computer Modbus RTU communication protocol.
4. Optional design and installation of magnetic stirring system, which can directly perform magnetic stirring on samples placed in beakers in the constant temperature bath workshop, without the need for an external vertical mixer, reducing redundant operations, and achieving closed processing to reduce fog loss during the stirring process.
5. Optional cooling coils built into the tank can quickly cool and control the exothermic reaction of the system.
6. Optional height adjustable immersion platform for easy adjustment of the liquid level of the immersed sample.
