Pneumatic Hand Pumps with no Gauge Connection (scissor handle) AP0V (300 psi / 20 bar) The quickest and most economical way to perform pneumatic field pressure calibrations on pressure transmitters, switches or gauges using an external pressure calibrator as the reference. Features: • Pressure calibration can be performed without electricity or nitrogen to 300 psi • Two outlet ports allow the user to attach pump to both device under test and external pressure reference thus eliminating a tee • Fine adjustment piston allows the user to achieve an exact pressure for cardinal point pressure calibrations • 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 sealant or a wrench • Rugged, all metal construction improves temperature and pressure stability • Made in U.S.A.
