Description
The DVR 3pro is a fully electronic, versatile vacuum gauge with ATEX approval for use in areas with potentially explosive atmospheres (ATEX category 2). Thanks to the easy operation and the combined digital/analog pressure display, measured values can be viewed fast and precisely. The DVR 3pro has an integrated pressure sensor made of aluminum oxide ceramic with excellent corrosion resistance and high long-term stability. A particular advantage is the flexible use with 9V battery power supply (mains-independent operation). Approved batteries are available from retail outlets. The removable cover at the back of the gauge allows for easy battery replacement. (Note: battery replacement must be done outside the hazardous ATEX area.)
