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
