Abstract

The sensor apparatus of the present invention includes on a nonconducting substrate (11) electrically conductive pathways (20, 22, 24) leading to at least two analyte electrodes (32, 34) and one reference electrode (36). The analyte electrodes (32, 34) each have sensitivities for both analytes but each has a membrane (48, 52) and/or electrolyte (50, 54) that favors the conversion of ionic potential to electronic potential for a different analyte. The apparatus has a fluid circuit means (68) for liquid contact between the electrodes (32, 34, 36) so that electric signals can be sent by electric circuitry (16) to an analyzing means (116). The analyzing means (116) determines the values of the analytes from simultaneously mathematical relationships.
