Vacuum controller VNC 2

VNC 2

The vacuum controller VNC 2 makes automatic, on-demand vacuum control possible either via two-point valve control or by switching the pump on/off. The version VNC 2 VARIO offers continuous vacuum control with VARIO^® pumps. The integrated alumina ceramic diaphragm vacuum sensor is chemically resistant and offers outstanding measuring accuracy independent of gas type. The VNC 2 vacuum controller is designed for precise and reliable control of recurrent routine jobs that do not require regular adjustment. It works with components compatible with the VACUU·BUS^® system. Special versions of the controller, e.g., for mounting into laboratory furniture are available. Further information on request.
