Vacuum gauge DVR 2pro Vacuubrand

The DVR 2pro is a fully electronic, versatile vacuum gauge for the measuring range from atmospheric pressure to 1 mbar. All wetted parts are made from enhanced chemical resistant material which allows the use under very rough laboratory conditions. The high accuracy and the large graphical display from the DVR 2 have also been carried forward for the “pro” version. One of the main enhancements is the power supply with a normal 9 V Alkaline battery. The new battery slot at the back of the gauge allows for easy replacement of the battery. A wider range of connection parts provide a great range of connection flexibility for laboratory use.
 

Performance features

• 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
