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
