Oxygen Sensor - Diving Applications

Diving Applications

The diving type of oxygen sensor, which is sometimes called an oxygen analyser or ppO₂ meter, is used in scuba diving. They are used to measure the oxygen concentration of breathing gas mixes such as nitrox and trimix. They are also used within the oxygen control mechanisms of closed-circuit rebreathers to keep the partial pressure of oxygen within safe limits. This type of sensor operates by measuring the electricity generated by a small electro-galvanic fuel cell.
