Volume Controllers

Perform both ultra-precise low-pressure differential or high-pressure static pressure calibrations with nitrogen using the same device with 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.
  • Fine adjust piston, fill, balance and vent valves are in one light weight, compact unit
  • Includes handle, Quick-test Systemâ„¢ outlet connections, hoses and adapters
  • Low volume Quick-test hose, gauge adapter and process connection can be attached to QTVC without thread sealant or a wrench
  • Soft-seated valves make filling and venting the system very precise
  • Included stand for laboratory or table top use (QTVC-LKIT)
  • Optional padded strap for field use (NPAK-STRP)
  • Made in U.S.A.
