Nitrogen Dioxide Calibration Standards for Portable Monitors

as-advertised NO 2 concentrations, the sensor response is greater in nitrogen mixtures than in air mixtures. 2. If, as filled initially, the two calibration mixtures had equal NO2 concentrations, then the oxygen and the NO2 in the NO2-in-air mixture may be reacting in the cylinder to reduce the NO2 concentration in the cylinder over time. 3. The air-diluted cylinder as initially filled had a ...

Nitrogen oxide sensor - Wikipedia

A nitrogen oxide sensor or NO x sensor is typically a high-temperature 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 ...

The challenges with electrochemical NO2 sensors in outdoor ...

2018-07-23· A nitrogen dioxide (NO 2) sensor would only detect NO 2 and a carbon monoxide (CO) sensor would only detect CO and so on. While electrochemical sensors are designed to be as specific as possible, most will respond in some manner to gasses other than the target gas. This is called “cross-sensitivity” and is a result of the interfering gas also reacting on the sensor …
