The Standard vacuum accessories include:
High Vacuum Station
Mobile cart size: 600 (L) x 600 (W) x 700(H), mm
Max. Loading: 600 Lbs on top
Molecular pump control Panel: LCD digital
Inside: Pfeiffer vacuum pump
Vacuum sensor is included
The vacuum sensor has a KF-25 connector.
High vacuum gauge (measuring range 10^-8 mbar ~ 10^3 mbar)
One button operation - the diaphragm pump and the turbomolecular pump will start after pressing the "start" button.
System controlled spinning speed - the controller will control the speed of the turbine spinning up and down according to the vacuum level and leaking rate of the reaction chamber.
Self-protection - the system will protect the pump from damage by overheating and overcurrent if the leaking rate of the reaction chamber is too high to achieve the high vacuum.
LCD screen - double lines parameters checking interface make the working easier to be handled.
