Pneumatic Pressure / Vacuum Hand Pumps (Direct Reading)  DPPV (100 psi / 7 bar) pressure, (-25/-635 mm Hg) Vacuum

This ideal solution for either differential pressure or vacuum calibration using a precision test gauge or pressure calibrator as the pressure reference.

Features:

• Generate either 100 psi (7 bar) or -25" Hg (-635mm Hg) vacuum with the same pump
• Unique design allows the user to convert from pressure to vacuum by simply twisting the knob, even with gloves on
• Two outlet ports allows 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
• Low volume Quick-Test hose, gauge adapter and process connection can be attached to pump without thread sealent or a wrench
• Rugged, all metal construction reduces pressure changes due to temoerature fluctuations
• Made in U.S.A.
