A Polarographic Oxygen Sensor Designed for Sewage Work and Field Application
Numerous designs of polarographic oxygen sensors (POS) have been described in the literature  and it may at first sight seem superfluous to add to this extensive list. A survey of the sensors available from various manufacturers reveals no striking differences in design. Most sensors have a gold or platinum cathode and an Ag/AgCl anode connected by an electrolyte. The choice of materials for the electrodes and the electrolyte is quite independent of sensor geometry; optimizing these parameters is not the aim of this article. I shall restrict myself, as a designer, to the geometry.
