ABSTRACT:
The present invention discloses a NOx sensor consisting of at least a pair of electrodes formed in touch with an ion conductive solid electrolyte; wherein the first electrode is composed of oxides of a metal (Cr, Mo or W) selected from 6a Group or a substance containing said oxides and an electric conductive material and the concentration of NOx in the test gas is detected by the change of the electromotive force between the first and second electrodes.
