The Divesoft R22S is a galvanic oxygen sensor made for gas analyzers. It is the standard replacement sensor for the Divesoft DNA, SOLO O2, SOLO, ECHO and He/O2, and it works in other analyzers built for a Molex 3-pin R22-type cell, such as the Apeks DSX analyzer accessory, Cochran Lifeguard, DiveTek Oz, DiveNav cootwo, Mares EANx and OxySpy. The R22S has no hydrophobic membrane and is not suitable for rebreathers. For closed circuit use, choose the Divesoft R22D or the Narked at 90 NaNM01.
Molex 3-pin connector, M16x1 thread. Measuring range 0 to 100% oxygen, accuracy ±1% of full scale at constant temperature and pressure.
Divesoft rates the expected service life at up to three years in air under normal conditions. In regular use, plan on replacing the sensor every 12 to 24 months, or sooner if it no longer calibrates reliably. Keep unused sensors unopened, ideally refrigerated, until you install them.
Galvanic oxygen sensors start aging on the day they are made, in storage as well as in use, so we list the manufacturing date of every sensor we sell. You will find it in the selector above.
Each sensor is registered under its own serial number and carries a 12-month limited warranty from Divesoft from the date of sale.
