A Polarographic Oxygen Sensor Designed for Sewage Work and Field Application

Conference paper


Numerous designs of polarographic oxygen sensors (POS) have been described in the literature [1] 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.
