The measuring gas diffuses through a membrane to a thin layer of electrolyte. At the cathode the
oxygen reduces. The free flowing electrons are drifting to the Anode. This generates a electrical
current which is direct proportional to the oxygen concentration of the measuring gas. The use of
electrochemical sensors allows in standard applications the measurement of trace oxygen in a number of complex and aggressive gas mixtures. The fitting sensor for a specific application has to be selected considering the different available electrolytes and electrodes. It is therefore essential to know the physical and chemical application parameters such as temperature, gas pressure, humidity content and the consistency of a specific measuring gas.
