Vacuum Gauge DVR 3 (ATEX)

Vacuum gauge

ATEX II 2G EEx ia IIC T4, e.g. for use in zone 1

1080 - 1 mbar (hPa)

The DVR 3 is a fully electronic vacuum gauge with ATEX certification for use in areas with potentially explosive atmospheres (ATEX category 2). The DVR 3 has an integrated transducer made of alumina ceramic with very good corrosion resistance and superior long-term stability. The DVR 3 also has the advantage of being battery-operated. Its simple operation and the combined digital/analogue vacuum reading for quick trend detection make the DVR 3 very versatile. The DVR 3 is a vacuum gauge without sensitive mechanics ans is used in chemical laboratories and process industries, plant and process technology.

Advantages

  • ATEX certification for category 2, e.g. for use in zone 1
  • analog display and digital readout: fast tendency detection, clear and precise readout
  • integrated capacitive gauge head made of alumina ceramic: excellent measuring precision and very good corrosion resistance
  • fully electronic – no fragile mechanical components
  • independent power supply unit BVE 9 V, with ATEX approval, mercury and cadmium-free
  • battery level indicator
