Pro-Leaf CO2 Controller & Regulator Bundle The Pro-Leaf Regulator is controlled by the Pro-Leaf CO2 Controller. It can be attached to a CO2 bottle and the controller will turn it on or off to increase the CO2 to your desired set point. Coupled to the Pro-Leaf Controller, this regulator is maintenance free and there is no way it can freeze open like many of the other regulators on the market. Simple to use Constructed from solid brass Two pressure dials: (1) gas pressure and (2) flow rate Simply set the desired CO2 level for the time of day, and the Pro-Leaf CO2 Controller will maintain that level. Day & Night mode, detected via a light sensor Accurate infrared CO2 sensor Large digital display to check CO2 levels and set point Accurate, self-calibrated sensor Bandwidth setting ensures the unit will not switch on and off too quickly Fuzzy logic to prevent freezing of CO2 regulators
