ISTA CO2 Bubble Counter with Check Valve

CHARACTERISTICS

• Two functions design, CO2 bubble counter and check valve.
• Accurate CO2 bubble reading.
• Good quality silicate material of check valve avoids backflow

Specifications

What it is. A combined CO2 bubble counter and check valve in one fitting: placed inline on the CO2 tubing between the regulator and the diffuser.

Two jobs, one part. The counter chamber lets you see and count CO2 bubbles to judge your injection rate; the check valve inside stops tank water from siphoning back up the line toward the regulator if pressure drops.

Build. Acrylic counter body with a silicone valve seal, built to resist the hardening a lesser rubber compound would suffer under constant CO2 exposure.

Setup. Fill the counter chamber roughly two-thirds full of water before connecting the CO2 line: that’s what lets you actually see and count the bubbles rather than just gas passing through empty.
