• A wide range of measurement and control, 1-1,000mbar.
• Two control modes of single-point control and programmed control available for choice as needed.
• Can store up to 5 programs, each containing up to 5 segments of programming control.
• A large-size TFT touch screen display control allows easy operation.
• All parts in contact with vapor or liquid are made of PTFE, ceramics or other high-performance materials and can effectively resist corrosion caused by organic solvents, water, acid and alkali.
• A built-in vent valve can feed inert gas into system equipment.
• One-stroke decompression allows easy installation and dismantling of vacuum system.
• Can be connected with pump power control for temporary shutdown of pump power supply after reaching stable degree of vacuum for energy conservation and environmental protection. Can also be operated in the normally open statue of pump.

1.How to connect the rotary steaming and vacuum controller, and what is the function of the vacuum pump?
The vacuum controller is connected between the rotary steamer and the vacuum pump, in series. When using a rotary evaporation evaporator, the vacuum degree is not appropriate, and the reagents will suddenly boil and bump. By using a vacuum controller, in series with the rotary evaporation, the internal vacuum of the rotary evaporation can be accurately controlled, especially for the concentration of volatile reagents, which can achieve the maximum The most ideal recovery rate. It is also widely used in the vacuum distillation of organic reagents, the gradual control of the vacuum degree, and the gradual extraction of solvents.
2.What is the working principle of the vacuum controller? How to achieve pressure control without using a pressure sensor?
When the vacuum pressure in the system is higher or lower than the set pressure, the pressure sensor in the controller will act immediately, and the switch contacts in the controller will be disconnected or connected. At this time, the equipment will stop working; when the vacuum in the system When the pressure returns to the set pressure range of the equipment, the pressure of the controller is reset immediately, so that the switch contacts in the controller are turned on or off, and the equipment is working normally at this time.
