Power : AC100-240VIs Smart Device : NOName : Carbon dioxide generator system kitMaterial: : aluminum alloy + stainless steelDIY CO2 generator reaction kitJust add citric acid, it can produce baking soda, bottled water, carbon dioxide. The metabolism rate of plants can be increased rapidly, thereby creating the best growth conditions for fish. This is the best choice for making CO2 equipment at home. It is simple, safe and economical.Purchase: choose as shown (A/B/C/D/E/S)Note: S version: water-filled bubble counter (can be directly filled with water during equipment operation)specification:Main material: aluminum alloyMain color: silverPower supply: input AC100-240V output DC12VFunction: suitable for power supply AC110V-AC220VCountries/regions that provide 110V or 220V powerOne bottle: 200g citric acid + 600g waterBottle B: baking powder 200g + water 200gnotes:1. Do not open the bottle directly under pressure, please wait for the automatic pressure relief.2. This product does not contain a reaction flask.main feature:It can be made of aluminum alloy + stainless steel. It is strong, durable and efficient.The lid and the pipe are well sealed, leak-proof, not deformed, and never loose.Professional pressure gauge for pressure monitoring.Continuously produce pure carbon dioxide through cheap, simple chemical reactions.Solenoid valve: control the opening and closing of the carbon dioxide generator system through a timer (not included).Bubble counter with check valve: The flow rate of the CO2 gas pressure gauge device can prevent water from being poured into the bottle.Equipped with a safety valve, the pressure is automatically greater than 4kg, and the pressure of the carbonated beverage bottle is 8kg to ensure safety.The safety valve supports manual pressure relief. When the pressure is lower than 4kg, you can manually release the pressure by pulling the ring of the safety valve. It is very safe.If you have any questions, please feel free to contact our store!
