DVR 2
Description
Digital / Analogue Vacuum Gauge DVR 2
Vacuum measurement in the range of 1080 - 1 mbar (hPa)
- Large analogue and digital vacuum display with
clear and precise readout - mains-independent operation for variable use
- excellent accuracy
The DVR 2 is a fully electronic, versatile vacuum gauge for the measuring range from atmospheric pressure to 1 mbar. The DVR 2 has an integrated capacitive transducer made of alumina ceramic with outstanding corrosion resistance and superior long-term stability. A particular advantage of the DVR 2 is its mains-independent battery operation. Its simple operation and the combined digital/analogue vacuum reading for quick trend detection and precise readout make the DVR 2 very versatile. It meets high requirements concerning accuracy, safety and environmental protection.
Advantages
- Large analogue and digital vacuum display: quick trend detection, clear and precise readout
- integrated capacitive alumina-ceramic transducer: very good corrosion resistance and long-term stability
- fully electronic – no fragile mechanics
- User-selectable pressure units (Torr, mbar, hPa)
- Digital calibration
- EMC-compatible
- Mains-independent operation
