Ralston DPPV-0000 125 PSI & Vaccuum Pneumatic Calibration Pump

Generate either 125 psi (8.6 bar) pressure or 23 inHg (584 mmHg) 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, eliminating a tee. Large-volume, fine-adjustment piston provides precise control, even at very low pressure. Precisely vent pressure with soft-seated bleed valve. Generate either a vacuum or a pressure for calibrating low pressure, or vacuum instrumentation using an external pressure calibrator.   Max Pressure 125 PSI / 8.6 bar / 860 kPa Max Vacuum 23 InHg / 77.9 kPa Materials Anodized Aluminum, Brass, Stainless Steel Outlet Port Male Quick-test, Male Quick-test with cap and chain Seal Materials Buna-N, Delrin Pressure Media Air Min Operating Temperature 0 °F / -18 °C Max Operating Temperature 130 °F / 54 °C Fine Adjustment Resolution 0.01 PSI / 0.07 mbar / 0.00 kPa Media Compatibility Air, Inert Gas, Natural Gas Data Sheet User Manual
