The most cost effective way to perform pressure calibration with one compact, lightweight unit. Easy to use and #151;just quickly attach or detach reference with one pressure gauge, calibrator or pressure module connection. A fine adjustment piston allows precise pressure control. The Delrin and reg; acetal, soft-seated fill and bleed valves allow for small adjustments to pressure. Also included are low volume hoses which conserve nitrogen in the cylinder so it lasts longer. The stainless steel calibration manifolds are ideal for remote field calibration to 5000 psi (345 bar). Quickly and economically calibrate high-pressure instrumentation using nitrogen Proprietary pressure balanced fine adjustment piston allows for precise control of pressure up to 3000 psi (207 bar) Fine adjust piston, fill, balance and vent valves are in one light weight, compact unit Soft-seated valves make filling and venting the system very precise Low volume Quick-test hose, gauge adapter and process connection can be attached without thread sealant or a wrench.
