The O2EII Pro O2 Analyser is a compact and accurate device to analyse the Oxygen content of your nitrox mix for diving. It is robust, simple to use and reliable.
Having your own analyser gives you peace of mind knowing you have properly checked the contents of your cylinder before a dive and especially after any air top-ups - to make the most out of your original fill.
O2EII Pro O2 has been the preferred choice of nitrox analysers for scuba divers for years. It comes with a 3 year graded sensor warranty and has an expected sensor life of 4 to 5 years in air.
Why?
In order to plan for a safe dive, you need to know the concentration of oxygen within your dive gas mix.
Monitoring the oxygen levels within your gas mix will determine your entire dive plan allowing you to plan the depth, time and decompression stages allowing for a care free dive.
The new addition of the Hose Barb has been created to save you time and allow for ease of use use when checking your mix while your tank is connected to your first stage regulator (via your BCD's low pressure inflator. Please note a BCD low pressure inflator flow restrictor is required. Check with your BCD manufacturer for the correct model.
Where?
The O2EII Pro is a portable nitrox analyser which is small, lightweight and rugged. It can easily be taken on all of your diving adventures.
The O2EII Pro can be used to check the quality of your diving gas mix directly at the tank or through your BCD adaptor while in your harness.
With the unit Analox provides an oxygen compensation chart, which enables the unit to be used in all environments around the globe. This enables the user to correct the unit based on temperature and humidity.
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.
