Vacuum gauge DVR 4 / DVR 4S

Vacuum gauge measuring range1080 - 1 mbar
(rough vacuum)

II 1/2 G EEx ia IIC T5
ATEX-category 1/2

The product

The VACUUBRAND DVR 4 / DVR 4S is a fully electronic total pressure vacuum gauge with ATEX approval for the intended use in potentially hazardous areas (category 2, e.g. zone 1; measurement part category 1, e.g. zone 0). The integrated pressure transducer made of alumina ceramics is highly corrosion and overload resistant. Automatic sleep mode (selectable time setting, factory setting: 15 min) and user-selectable operating time provide long operating time for the battery-operated vacuum gauge.
The DVR 4 / DVR 4S is a rugged electronic vacuum gauge without sensitive mechanics suitable for use in the chemical industry, technology and process technology. The reading is independent of the nature of the gas.

The particular advantages

  • ATEX approval category 1/2, e.g. for use at zone 0
  • analogue display and digital precision: clear trend indication and easy to read
  • transducer made of alumina ceramics: high corrosion resistance, excellent long-time stability
  • fully electronic instrument, no sensitive mechanics
  • battery operated; long operating time: automatic sleep mode, user-selectable operating time, low battery indicator, exchangeable at hazardous area
  • reading independent of gas
  • digital calibration
  • user selectable vacuum units (Torr, mbar, hPa)
  • measuring results data transfer via current interface (DVR 4S) (4-20 mA)
