Product description

Divesoft Oxygen Sensor – Type R22D (Molex)

The Heart of Your CCR Loop

The Divesoft R22D Oxygen Sensor is a high-precision galvanic fuel cell designed for use in closed-circuit rebreathers (CCR). As the primary method for monitoring the partial pressure of oxygen (ppO2) in your breathing loop, reliability and accuracy are non-negotiable.

This specific model (R22D) features a hydrophobic membrane to repel moisture and ensure consistent readings in the humid environment of a rebreather loop. It connects via a standard 3-pin Molex connector and screws in using an industry-standard M16x1 thread.

Quality Assurance: Every sensor is individually tested and registered under a unique serial number to track manufacturing dates and batch quality. Divesoft guarantees these galvanic sensors with a limited 12-month warranty from the date of purchase.


Key Features

  • CCR Optimized: Designed specifically for the humid, hyperbaric environment of a rebreather loop.
  • Standard Connection: Equipped with a 3-pin Molex connector widely used in modern rebreather electronics.
  • Traceability: Each sensor bears a unique serial number for age verification and warranty tracking.
  • Membrane Protection: Hydrophobic face helps prevent water droplets from blocking the sensor surface.

Technical Specifications

  • Model: R22D
  • Connector: Molex (3-Pin)
  • Thread Size: M16x1
  • Sensor Type: Galvanic / Electrochemical
  • Warranty: 12 Months (Limited)

Why You Need This

Pro Tip: Oxygen sensors are perishable items with a finite lifespan. We recommend replacing your sensors annually or whenever they show signs of drift/current limiting. Always verify your specific rebreather's compatibility—while the R22D fits the Divesoft Liberty, it may also fit other units requiring Molex/M16 configurations.
