This application note contains explanation such as oxygen concentration, equation, dissolved oxygen sensor, oxygen, temperature, reaction, application, and membrane permeability. There are lots of discussion such as cathode, current, the partial pressure, process measurement, the oxygen concentration, response, and electrode materials are described in this application note.
Inside this application note you can read things around oxygen sensor, measurement, water, oxygen diffusion, galvanic sensors, sensor, and voltage. Here are some excerpt from this application note:
Application Note Dissolved Oxygen Sensor Primer TruDO Dissolved Oxygen (DO) is the term used for the measurement of the amount of dissolved oxygen present in a unit volume of water. In bioprocess applications, such as cell culture or fermentation, the level of DO must be kept high enough for the organisms to thrive, but not so high as to cause unnecessary turbulence during the aeration of the water. Although dissolved oxygen (DO) is usually displayed as %, mg/L or ppm, DO sensors do not measure the actual amount of oxygen in water, but instead measure the partial pressure of oxygen in water, which is dependant on both salinity and temperature.
In addition, the application note contains info regarding probe, pressure, saturation, dissolved oxygen, anode, oxygen permeable, and electrolyte.
