Advisory Notes:

1) We are aware that there are a number of alternative sensors on the market, some of which are cheaper, but none that we have seen are designed to mate correctly with the O2EII. For more information please read 'O2EII - replacement O2 sensors'.

2) Replacement oxygen cells for the O2EII should only be purchased when required. Analox do not recommend that spare cells are bought when purchasing your O2EII. Electrochemical sensors are consumable items. We therefore cannot credit sensors if incorrect orders have been placed. This does not affect your warranty
