The revolutionary PV 411A (4 In 1) multi-function pressure generator is a remarkable new hand pump for generating vacuum, gas and hydraulic pressures from a few mbar up to 700 bar. The PV411A is the ideal field tool for applying test and calibration pressures to sensors, gauges, switches, indicators and recorders. It is also a low cost pressure source for workshops and laboratories. This wide capability removes the need to carry several hand pumps. Vacuum Applying vacuum to absolute, negative gauge and differential field instruments is no longer a problem. With just a few strokes, the PV 411A generates up to 95% vacuum (-950 mbar at 1000 mbar ambient).
