<p>An electrolytic sensor (10) is set forth for measuring the amounts of an ionic and of a vaporous species in a liquid. The system has an electrode (16) sensitive to an ionic species and another electrode (22) sensitive to a vaporous species. A unitary membrane (20) covers the electrodes and the requisite electrolyte with the membrane being permeable to the vaporous species, impermeable to the liquid and having dispersed in it an ionophore which senses the ionic species via selective transfer into the membrane of a quantity of the ionic species determined by the concentration of the ionic species in the liquid. Such quantities as hydrogen ion concentration, carbon dioxide concentration and oxygen concentration can be determined by a single electrolytic cell structure.</p> |
