Self contained unit provides a precise nitrogen source for calibrating differential and static pressure instrumentation using an external pressure calibrator. Proprietary pressure balanced fine adjustment piston allows for extremely precise, finger-tip control of pressure at 0.03 psi (2 mbar) or 3000 psi (210 bar) or any range in between. Easily refillable nitrogen cylinder holds enough gas for multiple calibrations. Nylon bag to hold hose and fittings attached to inside of lid. Includes storage compartment in control panel for pressure reference test gauge. Low volume Quick-test hose, gauge adapter and process connection can be attached to NPAK without thread sealant or a wrench. Designed to meet US Department of Transportation (DOT) and Canadian Transport Canada (TC) standards.
