Title:
METHOD AND APPARATUS FOR CONDITIONING A SENSOR FOR MEASURING OXIDATION REDUCTION POTENTIAL
Document Type and Number:
WIPO Patent Application WO2006033778
Kind Code:
A3
Abstract:
A method and apparatus for conditioning a sensor (100) to measure an oxidation reduction potential of an aqueous solution (104) such that the time to obtain a reliable oxidation reduction potential measurement is substantially reduced. Such conditioning is often necessary when the sensor (100) is moved from potentiometric equilibrium (e.g., the sensor is cleaned, the sensor is exposed to air, and the like). The method may comprise generating a current through a measurement electrode (108) and a reference electrode (112) of the sensor (100) for a duration of time. A reliable oxidation reduction potential measurement can be made as the voltage across the measurement electrode (108) and the reference electrode (112) stabilizes after the duration of time. Depending on the aqueous solution (104), the stabilized value can be constant or variable.
