Abstract

It is disclosed an apparatus and method for determining a temperature of the bath of an electrolytic cell during electrolytic production of a metal. The apparatus comprising an electrode body and a conductor pin at least partially inserted thereinto for providing electrical connection; and a probe inserted into the conductor pin, for providing one or more probe readings and being operable when positioned at least partially below a bath-vapor interface upon immersion in the electrolytic bath. The temperature of the bath is determined based on at least one of the one or more probe readings. The probe is protected from corrosion by the conductor pin during metal production. The electrolytic 10 cell may comprise more than one apparatus for measuring temperature in order to evaluate a temperature profile in the bath. Preferably, the one or more anodes are inert or oxygen evolving anodes, and the metal to be produced is aluminum.
