The DVR 3pro is a fully electronic, versatile vacuum gauge with ATEX approval for use in areas with potentially explosive atmospheres (ATEX category 2). Thanks to the easy operation and the combined digital/analog pressure display, measured values can be viewed fast and precisely. The DVR 3pro has an integrated pressure sensor made of aluminum oxide ceramic with excellent corrosion resistance and high long-term stability. A particular advantage is the flexible use with 9V battery power supply (mains-independent operation). Approved batteries are available from retail outlets. The removable cover at the back of the gauge allows for easy battery replacement. (Note: battery replacement must be done outside the hazardous ATEX area.)

Performance features

  • Flexible application range due to mains-independent operation of the fully electronic vacuum gauge with ATEX approval
  • Large, graphical analog display combined with precise digital readout allows users to detect and view tendencies easily
  • Improved functionality within the navigation menu helps to save energy and to increase the life cycle of the battery; battery easily replaceable; no lithium battery
  • High reliability, low EMI emission level near detection limit, high degree of immunity to electromagnetic interference, suitable for use in industrial environments
  • Capacitive ceramic diaphragm vacuum sensor made of aluminum oxide with excellent chemical resistance, accuracy and long-term stability
