This is a Brewin brand dual gauge CO2 regulator used for draft beer setups. The high pressure gauge reads between 0-3000 psi and the lower pressure gauge reads between 0-60 psi. There is an easy to turn knob which does not require any screw driver to adjust the pressure like other CO2 regulators and will easily dispense your beer consistently around 10 psi with little fluctuation in pressure. There is a shutoff valve for additional flow control.
