The CarbonDoser Electronic CO2 Regulator is the most reliable CO2 regulator on the market. Instead of traditional needle valves controlling the flow rate, the CarbonDoser uses an electric solenoid that will open and close within a fraction of a second producing a single bubble. Since there is no needle valve, the CarbonDoser's bubble rate will never change. You now have super precise control with unmatched reliability. An electronic solenoid controls the bubble rate, making it virtually impossible for it to ever change.
