Divesoft Oxygen Sensor – Type R22D (Molex)

Precision in the Loop.

The Oxygen Sensor is the most critical consumable in your Closed Circuit Rebreather (CCR). The Divesoft R22D is a high-precision galvanic fuel cell designed specifically for the rigorous demands of the Divesoft Liberty and other rebreathers using the Molex/M16 standard.

As the primary method for monitoring your ppO2 (Partial Pressure of Oxygen), reliability is non-negotiable. This specific model features a hydrophobic membrane engineered to repel moisture, ensuring consistent readings even in the humid, hyperbaric environment of a breathing loop.

Quality Assurance
