Divesoft Flow Limiter for 2nd Stage Hose (CCR Liberty Calibration)

The Key to Precise CCR Calibration.

The Divesoft Flow Limiter for 2nd Stage Hose is a specialized tool engineered for CCR Liberty divers. When calibrating Oxygen sensors, you need to flush the sensor chamber with a known gas (usually pure Oxygen) at a specific flow rate to ensure accurate readings without over-pressurizing the cells.

This device screws directly onto any standard Low-Pressure Regulator Hose (replacing your second stage). It restricts the flow to a consistent 0.8 – 1 L/min, creating the perfect environment for sensor verification.

Compatibility

• Connection: Standard 9/16-18 UNF (Fits standard scuba LP regulator hoses).

• Application: Specifically designed for the calibration ports on the CCR Liberty Head.

Important Usage Warning

• Not for Analyzers: This device has a flow rate (0.8 - 1 L/min) that is too high for standard Divesoft He/O2 Analyzers (which require ~0.2 L/min). Do not use this for general gas analysis.

• Calibration Only: This tool is intended strictly for flushing the CCR head during calibration procedures.

Technical Specifications

• Input Thread: 9/16-18 UNF (Standard LP Hose)
