Abstract:
1. A method of conditioning a sensor for measurement of an oxidation reduction potential of an aqueous solution, the sensor having a measurement electrode, a reference electrode, and a voltmeter to measure a voltage across the measurement electrode and the reference electrode, the method comprising: placing the measurement electrode and the reference electrode in the aqueous solution; removing at least one of the measurement electrode and the reference electrode from the aqueous solution; placing the at least one of the measurement electrode and the reference electrode back in the aqueous solution; generating a current through the measurement electrode and the reference electrode by applying a voltage to at least one of the measurement electrode and the reference electrode for a duration of time substantially immediately after placing the at least one of the measurement electrode and the reference electrode back in the aqueous solution; and measuring an oxidation reduction potential of the aqueous solution after the duration of time.
