ABSTRACT:
Disclosed is a sensitive glass film for a pH electrode, which is not deteriorated in its glass strength or pH-measuring function, which is hardly stained, and from which any stain can be removed easily. Also disclosed is a pH electrode having the sensitive glass film. A microparticle comprising rutile-type or brookite-type titanium dioxide or a microparticle comprising amorphous titanium dioxide is adhered directly on the glass film surface of a sensitive glass film for a pH electrode.
