Ralston Instruments DPPV-2MBA DPPV (+125PSI to -23inHg) Pump 1/4" NPTM Gauge Adapter, 3' Hose

Product Highlights

• Generate either 125 PSI (8.6 bar) pressure or 23 InHg (584 mm Hg) vacuum with the same pump
• Unique design allows the user to convert from pressure to vacuum by simply twisting a knob, even with gloves on
• Two outlet ports allow connection to reference pressure gauge or pressure calibrator as well as device under test, thus eliminating a tee
• Large volume fine adjustment piston provides precise control, even at very low pressures
• Precisely vent pressure with soft seated bleed valve
