Abstract
A multi-functional water quality sensor assembly includes an electrically non-conductive substrate carrying electrically conductive traces that comprise one or more electrodes configured to sense at least one of oxidation reduction potential (ORP) or acidity (pH) of water. The electrodes are configured to be operated according to a dynamic mode, which includes establishing constant potentials or constant currents between the electrodes and documenting potentials between the electrodes as a measure of ORP and/or pH, and/or determining a differential in the potentials between first and second times as a measure of pH of the water, wherein the dynamic mode may be carried out without use of a silver chloride reference electrode.
