Vacuubrand DVR 2pro Vacuum Gauge

The Vacuubrand DVR 2pro is a fully electronic vacuum gauge for the measuring range from atmospheric pressure to 1 mbar.

With all wetted parts made from enhanced chemical resistant material, this can be used under very harsh laboratory conditions.  The high accuracy and large graphical display from the DVR 2 have been carried forward on to this “pro” version.

One of the most significant enhancements of this model is the change to a normal 9 V Alkaline battery slot on the back of the gauge that’s easily accessible for quick replacement of the battery.  It also has a wider range of connection parts providing a great range of connection flexibility for laboratory use.

Performance features include:

  • improved functionality within the navigation menu helps to save energy and to increase the life cycle of the battery
  • large, graphical analog display with digital measuring values alows to detect tendencies and makes it easier to readout precisely
  • pressure unit user-selectable in mbar, hPa or Torr prevents unnecessary conversions
  • different vacuum connections and the additional support rod allow the use in almost every laboratory application
  • chemical resistant materials for wetted parts together with the capacitive ceramic diaphragm pressure sensor provide excellent long-term stability and accuracy
