Abstract
A method for in situ self-calibrating of an electrochemical sensor for measuring the concentration of one or more species in an aqueous medium. The method includes: taking a first measurement of the current of a working electrode representative of the concentration of dissolved oxygen in the medium, applying an anode current of predetermined density and duration to a generating electrode to produce a defined increase in the local concentration of the dissolved oxygen, taking a second measurement of the current of the working electrode representative of the concentration of oxygen after applying the anode current to the generating electrode, and computing from the first and second measurements a calibration factor for one or more species that relates the oxygen concentration of the medium to be analyzed and the actually measured current between the working electrode and its counter electrode.
