Nitrogen oxide sensor Wikipedia

A nitrogen oxide sensor or NO x sensor is typically a hightemperature device built to detect nitrogen oxides in combustion environments such as an automobile, truck tailpipe or smokestack. Overview. The term NO x represents several forms of nitrogen oxides such as NO (nitric oxide), NO 2 (nitrogen dioxide) and N 2 O (nitrous oxide, also known as laughing gas). In a gasoline engine, NO is the ...
