DOUBLE COUNTER by Cal Aqua Labs
Typical bubble counters allow the user to monitor CO2 flowrates up to 4-5 bubbles per second. Flowrates higher than this makes counting, and therefore monitoring, difficult to impossible. Cal Aqua Labs' Double Counter addresses this issue by offering a unique dual-function design that allows monitoring of both low and high CO2 flowrates within one unit.
