Measuring principle
The oxygen molecules that diffuse through the membrane are reduced at the cathode to hydroxide
ions (OH-). At the anode, silver is oxidized to silver ions (Ag+) (this forms a silver halide layer). A
current flows due to the electron donation at the cathode and the electron acceptance at the anode.
Under constant conditions, this flow is proportional to the oxygen content of the medium. This
current is converted in the transmitter and indicated on the display as an oxygen concentration in
mg/l, μg/l, ppm, ppb or Vol%, as a saturation index in % SAT or as an oxygen partial pressure in hPa.
