The oxygen sensor will have a longer life the less it is exposed to oxygen. So a good practice at the end of the analysis is to re-flood the inlet with pure air. If the unit does not have an auto power off system, remember to switch it off, otherwise you will run the risk to have a very low battery next time you use it. However, scuba tanks must meet oxygen service standards and be dedicated for use with enriched air. You’ll practice using oxygen analyzers and special cylinder decals. Your PADI Dive Center or Resort staff will explain other equipment you may need to enjoy enriched air diving. Non-vacuum-jacketed insulation should be oxygen-compatible due to the possibility of liquid air formation. "Air will condense at liquid hydrogen temperatures and can become an oxygen-enriched liquid due to the vaporization of nitrogen. Oxygen-enriched air increases the combustion rate of flammable and combustible materials." However, scuba tanks must meet oxygen service standards and be dedicated for use with enriched air. You’ll practice using oxygen analyzers and special cylinder decals. Your PADI Dive Center or Resort staff will explain other equipment you may need to enjoy enriched air diving.

Cylinder pressure analysis of a diesel engine using oxygen-enriched air and emulsified ... Any breathing mixture with an oxygen component greater than 21 percent is called enriched air nitrox (EAN) or simply enriched air. The term “enriched air” or EAN is preferable to nitrox because it more accurately describes the breathing mixture, and it avoids confusion with mixtures with less than 21 percent oxygen. A breathing gas is a mixture of gaseous chemical elements and compounds used for respiration.Air is the most common, and only natural, breathing gas. But other mixtures of gases, or pure oxygen, are also used in breathing equipment and enclosed habitats such as scuba equipment, surface supplied diving equipment, recompression chambers, high-altitude mountaineering, high-flying aircraft ... Extract: "Where medical oxygen consumption increases, steps must be taken to ensure the oxygen level (oxygen enrichment) is maintained below 23.5%." This is also detailed in EH40 and OSHA regulations. Enriched O2 poses a risk of hyperoxia on the human body as well as presenting an increased fire risk. this cylinder for oxygen or oxygen-enriched service (i.e. with any gas containing oxygen concentrations of 23.5% or more), all components used with the cylinder must be oxygen compatible. It is the responsibility of the cylinder user to ensure that the cylinder and all components are maintained in a The downside is that the maximum operating depth (MOD) for nitrox is less than air because the elevated oxygen may cause oxygen poisoning. Breathing EAN-36 at 130 feet would put the diver at 1.78 atmospheres of oxygen, well over the PADI/NAUI limit of 1.4.
