Analox Oxygen Analyzer


The O2 Portable Oxygen Analyser is designed to measure oxygen levels in the range 0.1 100% O2. The analyser should be used for cylinder oxygen level verification or for monitoring a gas mixing panel but should not be used for both. If the analyser is used for measuring the oxygen level in the output from a mixing panel, another O2 Portable should be used for cylinder verification purposes.

The O2 Portable has a large digital display and operates from an internal temperature compensated 3 year life (Expected) electrochemical oxygen sensor. Power is provided by a 9V, 4000 hour life battery giving up to 3 year operation before replacement is necessary. The O2 Portable is a water resistant drop resistant totally self contained unit designed specifically for all the diving industry Sport (NITROX), Commercial and Military where hostile environmental conditions are the norm not the exception.
