Best check of CO2: bubble counter and CO2/pH test.

Here a bubble counter is required to make the CO2 gas visible in the water, enabling the number of bubbles per minute to be counted.

The new JBL bubble counter doesn’t only provide the opportunity to accurately count the CO2 bubbles you add, it also contains a check valve, which safely prevents the backflow of the water to the CO2 unit.
