QD Flow Limiter

The Divesoft QD (quick-disconnect) flow limiter is an essential accessory designed for quick, efficient, and precise gas mixture analysis (He/O₂) directly from assembled and pressurized scuba cylinders. By utilizing the quick-release fitting of your inflator or another QD hose, this connector delivers a constant, low-pressure flow of 0.2 l/min at 10 bar. This allows you to analyze your gas mix seamlessly without the need to dismantle your second-stage regulator. Engineered with a 5.8 mm cylindrical connector, it easily attaches to your Divesoft gas analyzer via a standard connection hose. It is an ideal tool for both recreational and technical divers who demand accuracy, convenience, and safety during pre-dive gas verification.
