State-of-the-art vacuum gauges for laboratory and industrial operation have to meet high standards in terms of gauge head resistance to chemicals, reliability in rugged applications and operator-friendly interfaces. VACUUBRAND has a comprehensive range of electronic measuring instruments for the range of atmospheric pressure to 10-3 mbar.
A lot of applications in the laboratory call for electronic vacuum regulation, that is, constantly adapting the pump's volume flow rate to process requirements. The maximum volume flow rate of the unregulated pump can be changed in various ways:
- by cyclically turning the pump on/off (with the VNC 2 controller)
- by cyclically opening/closing an in-line solenoid valve (CVC 3000 or VNC 2) or
- by changing the pump´s motor speed continuously (VARIOTM pumps in connection with CVC 3000 or VNC 2 VARIO)
