The DVR 2 is a fully electronic, versatile vacuum gauge for the measuring range from atmospheric pressure to 1 mbar. It has an integrated ceramic diaphragm vacuum sensor with capacitive readout. The sensor measures independently of the type of gas and is exceptionally resistant to chemicals. It features outstanding measuring accuracy, very low temperature depencence and excellent long-term stability. A particular advantage of the DVR 2 gauge is its cordless, battery-powered operation. Its simple operation and the combined digital / analog vacuum reading for precise readout and quick trend detection, respectively, make the DVR 2 very versatile.
