Analytical Industries Palm O2D / Palm CO Flow Adapter (A-3671)
By Analytical Industries Inc. | Part # A-3671 | Fits Palm O2D & Palm CO Analyzers | Calibrated 2 LPM Flow Rate
Analyze your breathing gas without dismounting first-stage regulators. The genuine Analytical Industries A-3671 Flow Adapter connects directly to any standard low-pressure BCD quick-disconnect inflator hose, delivering a steady, regulated stream directly to your analyzer's sensor.
Designed specifically for the Palm O2D Oxygen Analyzer and Palm CO Carbon Monoxide Analyzer, this adapter incorporates a precision-drilled orifice that restricts gas flow to a constant 2 litres per minute (2 LPM). This eliminates sensor membrane over-pressurization and turbulence, ensuring accurate, highly repeatable Nitrox, Trimix, and CO readings before every dive.
Why Use a Calibrated BC Flow Adapter?
Cracking open a tank valve by hand can create backpressure and fluctuating flow velocities against the galvanic oxygen sensor, leading to false high or low FO2 readings. Connecting through your regulator's BCD hose via the A-3671 provides an exact 2 LPM flow regardless of first-stage intermediate pressure, protecting the sensing cell and giving you laboratory-grade verification at the dive site or fill station.
Key Features & Highlights
- No Regulator Removal Required: Analyze cylinders when already rigged—simply plug your BCD quick-disconnect low-pressure inflator hose onto the adapter nipple.
- Calibrated 2 LPM Restrictor: Integrated precision-drilled flow orifice delivers a constant, uniform 2 litre-per-minute stream to protect the galvanic sensor from overpressurization.
- Dual Analyzer Compatibility: Fully compatible with both the Analytical Industries Palm O2D Nitrox Analyzer and Palm CO Carbon Monoxide Analyzer.
- Standard 1/8" Tubing Barbed Fitting: Connects directly to standard 1/8" ID flexible sample tubing running to the analyzer flow diverter cap.
- Durable Marine-Grade Construction: Corrosion-resistant chrome-plated brass / Delrin hardware engineered to withstand harsh dive-boat environments.
