DVR 2

Description

Digital / Analogue Vacuum Gauge DVR 2

Vacuum measurement in the range of 1080 - 1 mbar (hPa)

  • Large analogue and digital vacuum display with
    clear and precise readout 
  • mains-independent operation for variable use
  • excellent accuracy

The DVR 2 is a fully electronic, versatile vacuum gauge for the measuring range from atmospheric pressure to 1 mbar. The DVR 2 has an integrated capacitive transducer made of alumina ceramic with outstanding corrosion resistance and superior long-term stability. A particular advantage of the DVR 2 is its mains-independent battery operation. Its simple operation and the combined digital/analogue vacuum reading for quick trend detection and precise readout make the DVR 2 very versatile. It meets high requirements concerning accuracy, safety and environmental protection.

Advantages

  • Large analogue and digital vacuum display: quick trend detection, clear and precise readout
  • integrated capacitive alumina-ceramic transducer: very good corrosion resistance and long-term stability 
  • fully electronic – no fragile mechanics
  • User-selectable pressure units (Torr, mbar, hPa)
  • Digital calibration
  • EMC-compatible
  • Mains-independent operation
