Constant O2 Monitoring Kit

Continuous, real-time oxygen monitoring for your hyperbaric chamber — measured the right way.

The Constant O2 Monitoring Kit installs outside the chamber and creates a small, precisely metered sampling line that continuously draws air from inside the cabin and delivers it to an external oxygen meter reading at ambient atmospheric pressure. That distinction matters: a sensor placed inside a pressurized chamber reads a distorted value because pressure changes oxygen's partial pressure. Sampling the air out and measuring it outside gives you an accurate, trustworthy number — every session.

• Universal fit for soft-shell and hard-shell chambers (confirm your exact chamber model with us before ordering — port configurations and fittings vary)
• Pressure-gated design: sampling begins only after the chamber passes 1.2 ATA, so it never interferes with door-seal engagement; built for continuous use at 1.3 ATA and above
• Precision metering valve controls a small, safe, continuous sampling leak — no impact on chamber pressure or dive profile
• Pairs with the Prestige Oxygen Analyzer Premium for a complete ambient chamber-air testing setup

Sampling Kit — $500 + $30 shipping. Includes the metering valve, tubing, and fittings needed to route chamber air to an external analyzer. Requires an oxygen meter (sold separately or as the combo below).

Combo Kit (Sampling + Oxygen Analyzer Premium) — $950 + $30 shipping. The complete solution — sampling hardware and a serviceable, field-recalibratable oxygen analyzer in one order.

Professional installation available. Contact us to confirm compatibility with your chamber before ordering.

This kit supports ambient-pressure air-quality monitoring and does not by itself constitute NFPA 99 certification or regulatory compliance. For chambers requiring documented compliance, see our OxySafe NFPA 99 Compliance Kit.
