ABSTRACT:
Oxygen sensor comprising solid oxygen-ion-conducting electrolyte with a platinum group metal film electrode contacts and monitors nonoxidizing or reducing gas atmosphere in a metal heat treatment (gas carburizing) furnace after a getter of the same platinum group metal as in the film electrode removes platinum group metal contaminants from such atmosphere before it contacts the electrode. Getter is held in a thin-walled, multi-passaged honeycomb body.
