    Volume Controllers

    $1,886.63$2,811.04
    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.
