Using a high quality copper carbon dioxide regulator, you can start adjusting the amount of carbon dioxide accurately and safely a simple but practical design Facilitates installation. Two manometers allow you to read the settings and make sure they are as you wish. The output pressure gauge automatically controls the output pressure and stabilizes at 4-6 bar after adjusting the bubble counter that can prevent reversal has a better resistance to the Corrosion and longer operating time, and can optimally provide plant carbon dioxide with plants and grow them magnificently the carbon dioxide controller can be used with our wall timer to perform a Automatic switching of the timer Our carbon dioxide regulator has been improved, the bubble counter with acrylic tube is thicker; The regulator body is copper. Everything is shiny silver, the design is more refined and easy to install. Main material: copper Silver Interface type: W21.8 Input voltage: 220V Size of the package: 21.5 * 18.5 * 9 cm
