Perform both ultra-precise low pressure differential or high pressure static pressure calibrations with nitrogen using the same device. Self contained nitrogen source, regulator, precision fine adjust, hoses, gauge adapters and process connections provide a complete pressure control solution for doing nitrogen calibration of pressure instruments in remote locations. 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 CE Approved for use in European Union - Designed to meet Pressure Equipment Directive (PED) and Transportable Pressure Equipment (TPED) standards Made in USA
