The Divesoft Oxygen Sensor 22S with a Molex three-pin connector is designed primarily as a replacement for oxygen sensors in all Divesoft gas analyzers (DNA, SOLO O2, SOLO, He/O2). However, it is also compatible with other devices, such as the Apeks DSX, Cochran Lifeguard, DiveTek Oz, DiveNav cootwo, Mares EANx, and OxySpy analyzers. The sensor operates within a range of 0–100% oxygen with an accuracy of ±1% across the full scale under stable temperature and pressure conditions. While the sensor typically lasts 36 to 48 months, heavy use can reduce its lifespan to as little as 12 months. For best accuracy, it is recommended to change the sensor every year. It is important to note that this sensor does not include a hydrophobic membrane, making it unsuitable for use in rebreathers. Each sensor comes with a unique serial number and is covered by a 12-month limited warranty from Divesoft.
