-30~200℃ Dynamic Temperature Control System
The heating circulator can realize dynamic temperature control from -25 ℃ to 200 ℃. It also has heating and cooling functions. The product has high efficiency, fast speed and simple filling. The whole liquid circulation is a closed system, without oil mist and water absorption, which ensures the safety of the experiment and the service life of the heat conduction medium. Using international brand compressors and circulating pumps, the performance is stable and the quality is reliable; the product has safety functions such as self-diagnosis function, refrigerator overload protection, high-voltage switch, overload relay, thermal protection device, etc.
