Hydrogen ion selective sensor and electrode therefor
Abstract
Abstract A hydrogen ion selective sensor has a sensing electrode with a palladium oxide coated palladium surface element and a reference electrode. A specific hydrogen ion selective sensor has a sensing electrode with a palladium oxide coated palladium surface element, a reference electrode spaced from and electrically insulated from the sensing electrode, an electrically insulating cover surrounding the palladium portion of the sensing electrode and the reference electrode, the cover defining an electrolyte chamber for containing a reference electrolyte therein, and a wick extending outwardly from the chamber adjacent the palladium oxide portion of the sensing electrode. An improved hydrogen ion selective sensing electrode is described which has a palladium oxide coated palladium surface element.
