2. Oxygen sensor - Wikipedia

   en.wikipedia.org/wiki/Oxygen_sensor

   The type of oxygen sensor used in most underwater diving applications is the electro-galvanic oxygen sensor, a type of fuel cell, which is sometimes called an oxygen analyser or ppO 2 meter. They are used to measure the oxygen concentration of breathing gas mixes such as nitrox and trimix . [ 9 ]

3. Electro-galvanic oxygen sensor - Wikipedia

   en.wikipedia.org/wiki/Electro-galvanic_oxygen_sensor

   Electro-galvanic fuel cell as used in a diving rebreather to measure the partial pressure of oxygen. Two oxygen cells as used by oxygen analysers for diving gas showing commonly used connectors. An electro-galvanic fuel cell is an electrochemical device which consumes a fuel to produce an electrical output by a chemical reaction.

4. Portable oxygen concentrator - Wikipedia

   en.wikipedia.org/wiki/Portable_oxygen_concentrator

   Portable oxygen concentrator used with bottle humidifier. POCs operate on the same principle as a home concentrator, pressure swing adsorption. [6] The basic set up of a POC is a miniaturized air compressor, a cylinder filled containing the sieve, a pressure equalizing reservoir and valves and tubes.

6. Gas detector - Wikipedia

   en.wikipedia.org/wiki/Gas_detector

   Oxygen fraction in a breathing gas is measured by electro-galvanic oxygen sensors. They may be used stand-alone, for example to determine the proportion of oxygen in a nitrox mixture used in scuba diving, [20] or as part of feedback loop which maintains a constant partial pressure of oxygen in a rebreather. [21]

7. Potentiometric sensor - Wikipedia

   en.wikipedia.org/wiki/Potentiometric_sensor

   Potentiometric solid state gas sensors have been generally classified into three broad groups. Type I sensors have an electrolyte containing mobile ions of the chemical species in the gas phase that it is monitoring. The commercial product, YSZ oxygen sensor, [1] is an example of type I.
