Detailed Description

The JJ-CCR Oxygen Cell (R17JJ-CCR) is an essential component tailored for use in JJ-CCR closed-circuit rebreathers. More than just a spare part, this sensor is an electrical lifeline - monitoring and enabling the control of oxygen partial pressure within your breathing loop. As an original manufacturer-issued part, it guarantees compatibility and calibrates perfectly with JJ-CCR systems.

To ensure peak reliability, these sensor cells are stocked in small batches to maintain freshness. The moment a cell leaves production is its “birth date,” and freshness is critical - older sensors can drift, degrade, or fail to calibrate correctly. Each cell arrives sealed in its original packaging, locking in calibration and shielding it from moisture or contaminants until you are ready to fit it.

The manufacturer specifies strict service life limitations: cells should not be used beyond 15 months from their production date, and once installed, their in-service life should not exceed 12 months. Following these guidelines is vital to ensure sensor accuracy, minimize calibration drift, and maintain diver safety.

With a lightweight, compact design, the JJ-CCR Oxygen Cell integrates seamlessly into your system without adding bulk, ensuring smooth performance even in demanding environments. Its robust build and strict quality control make it one of the most trusted oxygen sensors available for rebreather use.

Oxygen sensors are the heart of a rebreather system. They monitor oxygen levels and ensure that the loop maintains the correct setpoint. A fresh, factory-approved cell ensures predictable performance, reducing the risk of inaccurate readings. Worn or expired cells may misread oxygen levels or fail calibration, creating dangerous risks such as hypoxia or hyperoxia. Keeping fresh sensors installed is one of the most important safety measures in closed-circuit diving.
