ABSTRACT:
An improved thick film stannic oxide sensor is disclosed whereby the sensitivity of the sensor to CO is enhanced by the addition of a rare earth oxide to the sensor composition and the catalytic reactivity of the sensor, when contacted by a gas containing a reducing constituent, i.e., H.sub.2 or CO, and oxygen, is enhanced by employing RuCl.sub.3 or PtCl.sub.2 as a catalyst.
