Abstract
The electrochemical sensor for measuring concentrations of species in a fluid mixture is of the type comprising a partial-pressure internal reference electrode constituted by a system in which a metal is combined with an oxide of said metal. One face of the reference electrode is in contact with a solid electrolyte. An inert protective coating deposited on all the other faces of the electrode is impervious to the species which are present in the fluid mixture.
