Warning :
Many aftermarket oxygen replacement sensors, have dangerous readout errors in excess of 5% (as tested) due to lack of compatibility with the Analyzer. This type of error can result in you having a gas with a higher or lower PO2 than planned, possibly resulting in hyperoxia, hypoxia and even death!

Please note that the replacement Oxygen Cells offered by Oxychec for OMS oxygen analyzers fall into this category. We have extensively tested these cells and found that they can have a full scale error rate of up to 5%!

Play it safe and always use Original Equipment parts in your equipment.
