This is a screw-on type bubble counter for measuring the CO2 supply of the aquarium tank. It has a built-in check valve to prevent water back-flow from damaging the solenoid valve and is designed to be compatible with the most common type of CO2 regulators by attaching it to the needle valve.
The main body is made of solid brass construction with a nickel-plated coating which makes it durable and reliable for corrosion and wears resistance. The high transparency acrylic chamber enables you to accurately monitor the amount of CO2 injected into the aquarium.
