ABSTRACT:
A solid electrolyte gas sensor 10 is made, containing a body of solid electrolyte 14, in contact with a monitor electrode 12 exposed to a monitored gas environment 13 containing selected gas components to be measured, and in contact with a reference electrode 15 which is isolated from the monitored gas environment, where the solid electrolyte at the operating temperature of the gas sensor is effective to dissociate to provide the sole source of a self-generated gas, at the reference electrode 15, corresponding to the selected gas component to be measured.
