Abstract

Method and apparatus for measurement of the oxygen partial pressure or the oxygen content in a measurement gas in at least one measurement cycle using a solid electrolyte cell having at least one oxygen-conducting solid electrolyte, and having at least one reference electrode as well as at least one measurement electrode, wherein the at least one measurement electrode is in communication with the measurement gas and the at least one reference electrode is in communication with a reference gas or reference volume separated from the measurement gas, wherein a current is imposed via the electrodes on the solid electrolyte cell for pump operation and a measurement voltage (UM) is tapped at the electrodes.
