Why choose a DVR 2 Vacuum Gauge for Chemistry?
Announcement posted by John Morris Group 06 Oct 2015
Vacuubrand's 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/ analogue vacuum reading for precise readout and quick trend detection, respectively, make the DVR 2 very versatile.
When would I use a DVR 2? 
- Replacement of hazardous mercury “Mcleod” gauges
- Monitor vacuum on chemistry instrumentation for all brands of:
- Rotary Evaporators
- Vacuum Concentrators
- Vacuum Ovens
- Preventative maintenance monitoring of Rough Vacuum Pumps
