The Analox O2EII Pro Nitrox Analyser is the prefered choice of many professional divers and schools for accurate gas analysers to check your O2 mix before a dive. Essential for any EANx diver who needs to know what mix they are breathing to adjust your decompression algorithms.


Single Button Design hasn't changed from the previous model because of it's efficiency and the same calibrating dial make operation as simple as the previous model. Just as the previous model to analyse the mix in a cylinder you need to open the valve slowly so a small flow of gas comes out and place the dome section over the valve to pass the gas over the oxygen sensor.


BCD Adaptor Inlet has been added to the dome section that passes the gas to be analysed over the sensor so you can check your mix when assembled too. The new adaptor inlet allows you to connect your regulators to the cylinder and analyse the gas that comes through a low pressure inflator hose, so no fiddling with stiff valves trying to find that sweet spot that won't blow out the sensor. Simply connect your LPI to the inlet, gently open the cylinder valve and let your 1st stage adjust the gas flow. Please note, a BCD low pressure inflator flow restrictor is required and not included. Check with your BCD manufacturer for the correct model.
