ABSTRACT:
An improved electrode for a conductivity meter is provided formed of a titanium material cladded with platinum. The electrode is formed by immersing the titanium electrode form in an acid bath at an elevated temperature for approximately three hours. The surface of the electrode form is reduced in a relatively weak acid bath, and is then cladded by electrolysis with a platinum material to form a platinum black plating.
