Abstract
A probe for an electrochemical oxygen measurement pickup having an oxygen ion-conducting solid electrolyte with electrodes and electrical contact points connected by conductors to the electrodes, in which the probe has an electrochemically active region provided with the electrodes and an electrochemically passive region provided with the contact points as well as with their electrical connections to the electrodes. This minimizes or avoids false readings resulting from temperature gradient and changes in chemical equilibrium.
