Analox O2EII Nitrox Analyzer

The Analox O2EII® nitrox checker is a tried and tested analyser. It has taken the sport diving world by storm and is now the preferred analyser for nitrox divers. The O2EII® is quick and easy to use with 5 Simple Steps giving you the knowledge to plan for a safe dive.

As a nitrox diver, confidence in your mix is vital to an enjoyable, trouble free dive. Most diving associations stipulate in their training that you should never dive nitrox without being absolutely sure what your mix is, and therefore the use of a Nitrox Analyzer (also known as an Oxygen Analyzer) is essential.  

Analox has worked in the diving industry for over 25 years and we are specialists in designing analyzers to help look after the air you breathe. We manufacturer two different Nitrox Analyzers, both of which are suitable for beginners and the more experienced nitrox diver.  

The Analox O2EII™ nitrox checker is a tried and tested oxygen analyzer. Since its launch in March 2002 it has taken the sport diving world by storm. The O2EII™ is really easy to use with a simple 5 step process allowing you to plan for a safe nitrox dive.
