SONDE DE DETERMINATION DE LA TENEUR EN UN ELEMENT DISSOUS D'UN BAIN DE REVETEMENT

摘要

A probe for determining the content of a dissolved metal in a plating bath, comprising a tube (1) containing an electrolyte (3) in which the end of a wire made of said metal is immersed to form a reference electrode (4), and a tubular protective casing (11) around said tube. The lower end of the tube (1) is intended to be immersed in the plating bath and sealed by a sealing cap (2) made of a material with a melting point is lower than the bath temperature. The probe is particularly useful for measuring the dissolved aluminium content in a plating bath.
