Product Description DicI CO2 Bubble Counter DC06-03 With lock-nut design system, the bubble counter can effectively lock the C02 hosing and prevent the loose. Clearly shows the output of C02. (With function of non-return) Bubble counters with built in Check Valve are essential for determining the amount of CO2 that we inject into planted Aquariums. This device mounts directly onto to a CO2 Regulators needle valve. Remove an end cap and fill 3/4 with water. When installed it accurately measures the drop rate (drops p/sec). Has a built in Check Valve to prevent back flow into the regulator. This unit comes with the little o-ring required for the needle valve port just in case your needle valve doesn't have one. All CO2PRO regulators / Smart Alloy Splitters come equipped with o-rings preinstalled for your convenience.
