Our regulators enable the disbursement into the atmosphere of CO2 gas in conjunction with a CO2 controller. Titchmarsh supplied regulators are made of high grade brass fittings. The supplied regulators are electronically controlled regulators with a solenoid actuator. All regulators have the BS341/8 fitting required to connect to any standard CO2 valve. Our regulators come fitted with a gas pressure gauge showing the amount of gas pressure indicating the amount of gas left in the cylinder. When used in tandem with a CO2 PPM controller it provides the most reliable means of enriching CO2 levels within the environment.
