Pro-Elite Series, the Most Advanced Aquarium Dual Stage CO2 Regulator is the New Generation of our best-rated dual-stage regulator. This model has been appreciated by professionals all over the world. CO2Art is honoured to present you with the best aquarium CO2 Regulator ever. 

The Dual-stage design minimises an increase in output pressure as pressure drops in co2 cylinder and will prevent end-tank-dump keeping your aquarium safe and CO2 levels constant. The regulator is equipped with two gauges showing the tank volume and the flow pressure/working pressure. 

The most precise injection is possible thanks to a high precision needle valve with an integrated bubble counter allowing to adjust the pressure accurately. The customised manifold block is extendible, which means that you can run multiple diffusers with only one CO2 regulator. The pressure can be adjusted on each manifold separately allowing to run different CO2 levels in different tanks individually. 

The stem thread is made according to North America/CGA320 standard. This CO2 regulator is compatible with all CO2Art tubes and accessories. Pro-Elite CO2 Regulator provides you with a range of valuable features: 

• Safe 12V DC Integrated Solenoid Valve
