摘要： A Gas regulator capable of reducing the pressure of a gas supply from thousands of psi to as low as 30 psi with an accuracy level of +/−1 psi. The regulator uses at least two oppositely oriented gas stages to reduce the pressure. The first stage performs gross pressure reductions and subsequent stages perform fine pressure reductions. The regulator easily connects to commercially available gas bottles and can easily activate or deactivate gas flow without needing to disconnect the gas bottle. The regulator has a compact design and can provide readings which can be integrated into computer, online, or dynamic systems.
