Electric conductometer, electrode for measuring electric conductivity, and method for producing the same

摘要: An electric conductometer comprising a body made of conductive metal, at least two conductivity measuring electrodes having an electrode surface titanium oxide layer on the surface, space for storing substance to be measured formed between surfaces electrodes, and means irradiating with light. Since are layer, organic matters contained in system decomposed prevented automatically from adhering or being adsorbed surfaces. Consequently, can stably accurately all times without substantially requiring any cleaning.
