Description :

1.The low-temperature coolant circulation pump adopts a fully enclosed environmentally friendly compressor for refrigeration, and the system adopts internationally advanced non-fluorine environmental refrigeration technology, which has the advantages of energy saving and environmental protection.
2. The refrigeration system has multiple protection devices for overheating and overcurrent.
3. Temperature microcomputer intelligent control, simple operation, good temperature stability, upper and lower limit temperature alarm, PID brake control.
4. The large-screen LCD display adopts international display standards and has various function indicator icons for users to see at a glance.
5. The intelligent microcomputer can correct the temperature measurement deviation, and the temperature correction accuracy can reach 0.1°C.
6. PID for special users can be self-adjusted, with temperature self-adjusting function.
7. There are internal and external circulations. In the external circulation, the constant temperature liquid in the tank can be drawn outside, and a second constant temperature field can be established. It can also be used as a cold source (heat source) to draw the liquid outside the tank, and it can also lower (raise) the tank The temperature of the external experimental instrument extends the scope of application.
