Device for measuring the pH of liquid films.

摘要

The proposed device is suitable for measuring the pH of liquid films or limited volumes of electrolyte solutions and comprises a miniaturized electrode (11) made of a selected material sensible to the pH, which is put into contact with the electrolyte, a reference electrode (13) and preferably a polymeric saline bridge (12), it too in contact with the electrolyte and operatively connected with the reference electrode (11).
