Beschreibung
Zusammenfassung:	An electrochemical sensor apparatus and electrochemical sensing method within an aqueous system are described, using one or more working electrodes of boron doped diamond (BDD). A cathodic reduction process provides a cathodic measurement and, substantially simultaneously, an anodic oxidation process provides an anodic measurement. A sum of a content of two equilibrium species within the aqueous system is obtained using both the cathodic measurement and the anodic measurement. One example measures total free chlorine by simultaneously measuring hypochlorous acid (HOCl) and hypochlorite ion (OCl-).
