Abstract
A pH analyzer is operated to measure conductivity of a solution by applying a substantially DC current having peak values, I , to a reference electrode of an ion-sensitive sensor having an ion-specific electrode in contact with the solution. The reference electrode is coupled to the ion-specific electrode through the solution. The peak voltage, V , between the ion-specific electrode and the common electrode is measured, and the conductivity of the solution is identified based on
