Abstract
A method and apparatus for measuring the overvoltage of a gas producing electrode of a chlor-alkali diaphragm cell is disclosed. The method includes positioning an exposed metal tip of a reference electrode from about 0.2 to about 1.0 mm away from the gas producing electrode within a stream of gas produced by the gas producing electrode. The apparatus includes the reference electrode so positioned. Platinized platinum wire and a RuO.sub.2 --TiO.sub.2 coated Ti wire are preferred as the reference electrodes for cathode and anode, respectively.
