External circulation high-low temperature constant temperature circulator products provide laboratories with economical and environmentally friendly high-low temperature constant temperature circulation solutions. The compact structure design makes the appearance quite small, and it is very quiet when working. The small one can be directly placed on the desktop and used in the ventilation window, and the large one occupies a very small area. Three temperature control methods can be selected for the external circulation temperature control method: internal control, sample control, and tracking setting control. Users can control the Water Tank temperature, external material temperature, and slope control according to different temperature control methods. The program control type can also carry out 30-segment program control, and the user can easily set the program to realize multi-segment control such as heating, constant temperature, and cooling. It is especially suitable for temperature control of glass reactors, metal reactor jackets, temperature control of materials inside reactors, and any external application that requires constant temperature control.

1. Touch screen TFT display, touch operation, small size;
2. The combination of proportional refrigeration and PID control technology, CIT technology can directly cool down even at high temperature.
3. Maintenance-free pressure/suction pump, resistant to fiber and metal particles, long life, pump pressure and flow automatically adapt to external loads, effectively protecting external equipment, especially glass parts from damage;
4. Programmable control, you can edit 30 programs to realize liquid temperature heating, cooling, constant temperature and other combined control (optional)
5. The Water Tank is sealed, with an intuitive liquid level window, which is convenient for users to observe the liquid level. At the same time, 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 remind at the same time when alarming.
8. Light and sound remind at the same time when alarming, the buzzer can be set to be silent or sound, various alarm codes are directly displayed, and the error point can be directly determined
9. Internal and external Pt100 temperature sensors, which can perform single-point and two-point temperature calibration, and can control the temperature of external materials
10. A variety of operating modes are optional, and the power can be automatically restored in case of accidental power failure, which can ensure the continuous supply of cooling circulating water.
11. Optional intelligent control function: a variety of interfaces (RS485, RS232), through the input of 0-10V or 4-20mA analog signal to realize the remote control of the start/stop of the machine.
12. Environmentally friendly refrigerant, non-toxic pollution;
13. The maximum and minimum temperature settings of the machine can be limited
