This is an in-line 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 regulator and is designed to be compatible with most types of CO2 regulators.

The main body is made of solid brass construction with a nickel-plated coating, making it durable and reliable for corrosion and wear resistance. The high transparency acrylic chamber enables you to monitor the amount of CO2 injected into the aquarium accurately.
