The Analox O2EII Pro (the successor of the O2EII) is a portable oxygen analyser, generally considered to be the most reliable Nitrox analyser on the market. It is designed to measure the percentage of oxygen for tank oxygen level verification.

Analox O2EII Pro is robust and ergonomically designed to ensure a comfortable grip. It is small, portable and battery operated meaning it can be taken anywhere. It also has automatic switch-off after 10 minutes to ensure battery life is not compromised. It comes with an oxygen compensation chart, which enables the unit to be used in all environments around the globe. The user can correct the unit based on temperature and humidity. 

Designed specifically for the diving industry, whether it may be sport diving, commercial or military, the unit comes with a 3-year graded sensor warranty and has an expected sensor life of 4-5 years in air. The device is both water and drop resistant.

The addition of a spigot that takes the hose of a BCD adapter, now allows the unit to be used while checking air quality at the tank or while the user is connected to their regulator through a BCD’s low pressure inflator. (BCD adapter not included).
