Ralston Instruments APGV Pneumatic Hand Pump is a high pressure air pump with an integral test gauge fitting and a large diameter fine adjustment piston. This piston and the precision bleed-off valve give you precise pressure control. The scissor handle design, low internal volume and micro bore hose give you the advantage of reaching higher pressures with less effort. The swivel gauge fitting allows you to quickly match the gauge with the range being calibrated.
Portable, hand operated pump easily generates 300 psi (20 bar) without electricity or compressed air Light, compact pump can be easily transported to remote locations Fine adjustment piston allows the user to achieve an exact pressure for cardinal point pressure calibrations Precisely vent pressure with soft seated bleed valve Quick-disconnect gauge adapter allows changing test gauges without using a wrench Low volume Quick-test hose, gauge adapter and process connection can be attached to pump without thread sealant or a wrench Rugged, all metal construction improves temperature and pressure stability Made in U.S.A.
