Nitrogen Dioxide Gas Detector

Nitrogen Dioxide (NO2) is a toxic, corrosive, strong oxidising and non inflammable gas, very dangerous, that in concentrations higher than 4 ppm causes intoxication symptoms: eye, nose and bronchial tubes irritation and even death. The major sources of NO2 are diesel motor vehicles and combustion associated processes in petrochemical industries and power plants, as well as any high temperature combustion process used in industrial work.
