<strong>Vacuum</strong> gauge<br />
DVR 4 and DVR 4S<br />
The DVR 4 / DVR 4S are fully electronic vacuum gauges with ATEX approval <strong>for</strong> use in areas with potentially explosive<br />
atmospheres (measuring volume ATEX category 1, e.g., <strong>for</strong> zone 0). The integrated vacuum sensor made of alumina<br />
ceramic has an outstanding corrosion resistance and superior long-term stability. A particular advantage is its cordless,<br />
battery-powered operation. The combined digital / analog vacuum reading <strong>for</strong> precise readout and quick trend<br />
detection, respectively, as well as measurement readout out via current loop (only DVR 4S), make the devices very<br />
versatile.<br />
