The external circulation high-low temperature constant temperature circulator products provide an economical and environmentally friendly high-low temperature constant temperature circulation solution for the laboratory. The compact design makes it quite small and very quiet to work with, and the small ones can be used directly on the table and in the fume window, and the large ones have a very small footprint. There are three types of temperature control modes for external circulation: internal control, sample control, and tracking setting control, and users can control the temperature of the tank, the temperature of external materials, and the slope according to the different temperature control methods. The program control type can also carry out 30 stages of program control, and it is very convenient for users to set the program to achieve multi-stage control such as temperature rise, constant temperature, and cooling. It is especially suitable for temperature control of glass reactors, metal reactor jackets and internal materials of reactors, as well as any application where external needs require constant temperature control.

1. Touch screen TFT display, touch operation, small size;
2. Proportional refrigeration and PID control technology are combined, CIT technology can directly cool down even at high temperatures.
3. Maintenance-free pressure/suction pump, resistant to fiber and metal particle matter, long life, pump pressure and flow automatically adapt to external load, effectively protect the damage of external equipment, especially glass parts;
4. Programmable control, 30 programs can be edited to achieve liquid temperature rise, cooling, constant temperature and other combination control (optional)
5. Sealed Water Tank with intuitive liquid level window, which is convenient for users to observe the liquid level, and the Water Tank is equipped with a protective overflow port to prevent accidents;
6. Stable and reliable system: high-performance and high-quality spare parts, stable quality and reliable performance.
7. Multiple safety protection: water shortage protection, temperature protection, water pressure protection, overheating and overcurrent protection, light and sound can be reminded at the same time when alarming.
8. When the alarm is alarmed, the light and sound are reminded at the same time, the buzzer can be set to silent or sound, and various alarm codes are directly displayed, and the error point can be directly determined
9. Internal and external Pt100 temperature sensor, single point and two point temperature calibration, can control the temperature of external materials
10. A variety of operation modes are optional, and the unexpected power failure can be automatically restored, which can ensure the continuous supply of cooling circulating water.
11. Optional intelligent control function: a variety of interfaces (RS485, RS232), can remotely control the start/stop of the machine through the input of 0-10V or 4-20mA analog signal.
12. Environmentally friendly refrigerant, no toxic pollution;
13. The maximum temperature and minimum temperature settings of the machine can be limited
