The Druck PV622G is a pneumatic pressure generator for pressures 95% vacuum to 100 bar (1500 psi) pneumatic. Each pressure station is designed for stand-alone operation as a pressure generator and can replace conventional hand pumps to provide greater efficiency, ease of use and significantly reduce the risk of repetitive strain injuries. It can also be used on the workbench as a comparators. Combining any of the pressure stations with a PM 620 pressure module and the DPI 620G calibrator creates a uniquely capable, self-contained pressure calibrator.
