Many rebreather manufacturers do not wish to deal with global retail sales of oxygen sensors and publish generic sensor specifications suitable for their units, allowing the market to determine supply and price. Some rebreather manufacturers prefer to tightly control sensor availability, stating only their own branded sensor is approved for use in their unit. Regardless, Dive Gear Express has not done any verification or validation of rebreather oxygen sensors and disclaims any responsibility and liability for the use of oxygen sensors in rebreather applications. Verification and validation of specific oxygen sensors for use in rebreather applications is the responsibility of the equipment user and/or original equipment manufacturer.

Oxygen sensors are one of the very few items on our website that are NON-RETURNABLE., because we can't know with absolute certainty how they were handled once delivered. Additional shipping and handling of the return can also degrade performance. They are critical to safety in diving, and our customers have a reasonable expectation of receiving as factory fresh a product as possible from Dive Gear Express. Your complete satisfaction is our goal, so please consider carefully before purchase.
