ABSTRACT:
An electrochemical detector for measuring the oxygen content of the exhaust gases of internal combustion engines. The detector consists of a ceramic body having a catalytic electrode and a non-catalytic electrode, both of which are exposed to the flow of the exhaust gases and are separated along the surface of the ceramic body. In one embodiment, the ceramic body is a rod. In another embodiment it takes the shape of a cone.
