An oxygenmeter Its electrode function according to the Clark principle with platinum as cathode and silver as anode in an electrolyte cell to which a polarisation voltage is applied. Oxygen gas present in the electrolyte is reduced to OH ions at the platinum cathode. The resulting current is diffusion limited and therefore proportional to the oxygen concentration in the sample solution. This current is amplified, corrected and displayed in mg/l or % of dissolved oxygen.
