Ralston Volume Controllers
Perform both ultra-precise low pressure differential or high pressure static presssure 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 System™ 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.
