Pneumatic Pressure/Vacuum Hand Pumps with Gauge Connection Create pressure or vacuum and calibrate instrumentation using a pressure gauge or calibrator attached to the pump (gauge or calibrator not included) Features • 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 • Made in U.S.A.
