Abstract
A method and system for determining dissolved oxygen is disclosed. One or more constant currents are driven through amperometric-type dissolved oxygen probes to develop reference electrode potentials defining the envelope of oxygen electrochemistry. The reference electrode voltage is generally measured at a first current level and at a second current level utilizing the oxygen probe, wherein the first and second current levels define limitations of oxygen electrochemistry. An optimum electrode bias voltage can thereafter be automatically calculated based the reference electrode voltage measured at the first current level and the second level to thereby provide accurate indications of dissolved oxygen thereof.
