<strong>Vacuum</strong> gauge<br />

DVR 2<br />

The DVR 2 is a fully electronic, versatile vacuum gauge <strong>for</strong> the measuring range from atmospheric pressure to 1 mbar.<br />

The DVR 2 has an integrated vacuum sensor made of alumina ceramic with outstanding corrosion resistance and<br />

superior long-term stability. A particular advantage is its cordless, battery-powered operation. Its simple operation<br />

and the combined digital / analog vacuum reading <strong>for</strong> precise readout and quick trend detection, respectively, make<br />

the DVR 2 very versatile.<br />
