The Digital PPO₂ Monitoring Unit is an advanced, fully electronic measurement system designed for demanding underwater operations and closed‑circuit rebreather (CCR) applications. Engineered for reliability, accuracy, and deep‑water performance, the unit integrates state‑of‑the‑art solid‑state oxygen sensing technology with comprehensive dive‑parameter tracking.

Key Features

1. Fully Digital Architecture
   The device operates on a 100% digital platform, ensuring superior signal stability, noise immunity, and long‑term accuracy compared to analog sensor systems. All measurements, internal diagnostics, and data processing are handled through a high‑precision digital controller.
2. Solid‑State Oxygen Sensor
   Equipped with a next‑generation solid‑state O₂ sensor, the system delivers accurate partial pressure of oxygen (PPO₂) readings without the degradation issues typical of galvanic cells. This ensures longer lifespan, improved repeatability, and reduced maintenance.
3. Comprehensive Dive Parameter Monitoring
   Beyond PPO₂ measurement, the unit provides real‑time tracking of essential operational parameters:

• Oxygen pressure
• Depth
• Dive time
• Lung‑bag temperature monitoring for CO₂ scrubber absorbent management, improving safety and early detection of potential breakthrough conditions.

4. CO₂ Scrubber Temperature Control
   The system includes a dedicated thermal sensor to monitor the breathing loop’s lung‑bag temperature, allowing predictive insight into CO₂ absorbent performance and warning the diver of abnormal thermal deviations.
5. Data Logging & Download Capability
   All dive data are automatically recorded in onboard memory and can be downloaded post‑dive for analysis, documentation, and maintenance tracking via USB or wireless interface (depending on configuration).
6. Deep‑Rated Housing (200 m)
   The entire unit is built inside a rugged, corrosion‑resistant housing rated to 200 meters of depth, suitable for technical diving, military missions, and scientific marine operations.
