The O2EII Pro scuba analyzer is small, lightweight, and rugged. It can be used to check the quality of your scuba diving gas mix directly at the tank or through your BCD adaptor while in your harness.
With the unit, Analox Sensor Technology provides an oxygen compensation chart, which enables the unit to be used in all environments around the globe. This allows you to correct the unit based on temperature and humidity.
Monitoring the oxygen levels within your gas mix by using the O2EII Pro nitrox analyzer will determine your entire dive plan allowing you to plan the depth, time, and decompression stages allowing for a carefree dive.
