Abstract

A measuring arrangement for registering an analyte concentration in a measured medium includes a three electrode arrangement having a working electrode, a reference electrode and a counter electrode. The working electrode includes an analyte-insensitive, redox mediator, and the reference electrode a pH-sensitive electrode. The counter electrode can be formed of an inert, electrically conductive material. The measuring arrangement can be embodied to provide a desired voltage between the working electrode and the reference electrode and to register the electrical current flowing, in such case, through the measured medium, between the counter electrode and the working electrode.
