Simple, fast field testing for connecting a calibrator to a process connection. Connect this directly between the equipment to be tested and a reference. No need for a "T" joint.

Portable hand operated hydraulic pumps that easily generate up to 5000 psi (350 bar)
Two outlet ports allow user to connect to both device under test and external pressure calibrator thus eliminating a tee.
Fine Adjustment piston provides an easy way to achieve precise pressure
Vent valve is both durable and precise
Liquid reservoir holds enough fluid for multiple calibrations
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.
