High resolution low-temperature circulation is developed by various metrology, electronics, chemical, environmental protection, medicine, energy, refining, metallurgy, light industry, military and other departments and research institutes with extremely high requirements for constant temperature accuracy. After years of independent development, the integrated intelligent instrument temperature control is more accurate. Coupled with a specially designed non heat centrifugal circulation pump, the turbulent and highly uniform flow and temperature fields in the tank are achieved

Technical features:
Fully enclosed environmentally friendly compressor refrigeration system, CFC free.
● Temperature range: optional -50~100 ℃ (choose pure water, ethylene glycol, alcohol as the medium according to the temperature range);
● Temperature control function: Equipped with the latest generation of integrated PID automatic temperature control program, with a digital display resolution of 0.0001 ℃
Capacity range: 6L, 10L, 15L, 20L, 30L, 50L, 100L, and non-standard design and production can also be fully customized according to user requirements.
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.
● 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 device has low water level anti dry burning and explosion-proof functions
6. Multiple protection functions for compressor overheating and overcurrent
● 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 1-10 segment temperature control program, capable of automatic program temperature control and real-time display of set temperature time program operation status.
3. Optional RS232 or RS485 communication interface, easy to connect to the upper computer, with Modbus RTU communication protocol.
4. Optional design and installation of magnetic stirring system, which can directly stir the liquid sample in the beaker placed in the constant temperature bath studio with magnetic stirring
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.
7. Optional horizontal design, featuring compact structure, lowered center of gravity, and strong stability
