Abstract: A pH measuring combined electrode including a glass electrode, a reference electrode and a thermosensitive resistance element for temperature compensation integrated into a compact miniaturized assembly. At least the inner electrode of the glass electrode is constituted by a glass-coated lead-in wire and the thermosensitive resistance element is arranged in direct proximity to the inside wall of the pH sensitive glass membrane of the glass electrode. A guard ring is preferably provided around an electrode supporting tube to assist in maintaining clearance between the lead-in wires at their juncture with the electrode assembly.
