Analox O2EII

The Analox O2E2 Nitrox analyser an in depth description

As a nitrox diver it is essential for you to be confident in the blend of gas within your cylinder. Leading the way in nitrox analysers the Analox O2EII is simple to use and proven to be accurate whilst also being durable, so much so that it has been keeping divers safe for nearly a decade!

With a simple 5 step process you are able to clearly see the percentage of oxygen within your cylinder, once that percentage has been measured it is now possible to freeze the display to give you an accurate reading down to one decimal point.

MPN#SA1N01BG96N008#

The process is simple:

1. Turn the analyser on
2. Calibrate by setting the oxygen percentage and exposing the sensor to fresh air for two minutes
3. Turn the cylinder on (crack the pressure) and establish a gentle flow
4. Take a reading by holding the sensor close to the cylinder valve
5. The display will freeze, showing an oxygen percentage accurate to one decimal point

Any nitrox diver will know that having an analyser to depend on is essential, at Aquanauts we trust this analyser and use it day in day out in our centre. The analyser can be bought withoptional accessories: the Sensor Saver, Hygro Thermometer and foam lined Peli-Box.

We keep our analyser in the rugged Peli-Box and would recommend it to anyone thinking of purchasing the O2EII. It will protect it from literally anything a diver can think of throwing at it except maybe cylinders (if you can throw them). We also use ours in conjunction with the Hygro Thermometer. This means that when calibrating the analyser we can take into account the humidity and use the actual accurate oxygen percentage as oppose to the standard 20.9%. Moisture in the atmosphere along with the current temperature affects the percentage of oxygen found. Using the Hygro thermometer will ensure the highest accuracy of oxygen readings within cylinders, maximising safety. Therefore we recommend purchasing this as an extra.

With an expected life of four years the cells used to detect the oxygen will last for a long time. The Analox O2E2 cells are covered by a warrenty of three years, if required it is possible to replace the oxygen cells. We do not recommended that you buy replacement cells when purchasing the analyser as they are consumable items but rather purchase them as and when required.

The Sensor saver, if used when your unit is not in use, will extend the life of the O2 cells even further so for a few pounds you will be able to save on a much larger expense.
