Abstract
A solid state pH sensor having an indicator electrode of metal/metal oxide and a reference electrode of metal/metal salt applied to inert, electrical conductors imbedded in an electrically non-conductive substrate, such as a ceramic substrate. The sensing portion of the sensor preferably has a coating of an annealed perfluorocarbon copolymer. Alternatively, the indicator or reference electrodes may be formed on separate electrically non-conductive substrates with each having an inert electrical conductor imbedded therein. These indicator or reference electrodes may be utilized with each other or with prior art electrodes.
