Function and Applications

The DVR 2 is a fully electronic, versatile vacuum gauge for the measuring range from atmospheric pressure to 1 mbar. It has an integrated ceramic diaphragm vacuum sensor with capacitive readout. The sensor measures independently of the type of gas and is exceptionally resistant to chemicals. It features outstanding measuring accuracy, very low temperature depencence and excellent long-term stability. A particular advantage of the DVR 2 gauge is its cordless, battery-powered operation. Its simple operation and the combined digital / analog vacuum reading for precise readout and quick trend detection, respectively, make the DVR 2 very versatile.

  • high electromagnetic compatibility: Low emission level near detection limit, high degree of immunity to electromagnetic interference for use in industrial environments
  • large analog and digital vacuum display: Quick trend detection, precise readout
  • user-selectable pressure units (mbar, hPa, Torr)
  • digital readjustment
  • capacitive alumina ceramic diaphragm vacuum sensor with excellent chemical resistance, accuracy and long term stability
