    HV Station
    High Vacuum Station
    Structure 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
    Vacuum sensor The vacuum sensor has a KF-25 connector.
    High vacuum gauge (measuring range 10^-8 mbar ~ 10^3 mbar)
    Control Panel 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.
