Abstract
In a solid electrolyte electrochemical cell device for generating an EMF signal based on the Nernst equation which is indicative of the SO.sub.2 content of a monitored gas environment, the oxygen content of the reference environment of the cell is adjusted to maintain it equal with the oxygen content of the monitored gas environment to eliminate the effect of oxygen on the EMF signal measurement of SO.sub.2.
