This CO Reactor Set not only looks super cool but it also functions perfectly and creates pure CO from a chemical reaction. After this chemical reaction has taken place in the cylinder the CO gas is slowly and constantly released through a pressure regulator. The gas flow can be precisely adjusted with the adjustment knob and integrated bubble counter. The gas flow can be stopped at night with the solenoid which is included with the set and if you connect the solenoid to a domestic timer, you’ll have your CO coming on and off when your lights are on and off making the gas more economical.

This set includes:

• A stainless steel cylinder
• Pressure regulator
• Magnetic valve with timer
• Bubble counter
• Diffuser, and connectors.

CO2 component A & B are NOT included; these are sold separately

In addition, we recommend the Colombo Drop Checker which allows you to monitor your CO levels visually.
