NPAK-0000-0-0

Nitropak only, no gauge adapter, no hoses, no process connections

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
