Composite handheld nitrogen oxide gas detector with high temperature probe

Common nitrogen oxides include nitric oxide (NO, colorless), nitrogen dioxide (NO2, reddish brown), nitrous oxide (N2O), nitrous oxide (N2O5), etc. Among them, except for nitrous oxide which is a solid under normal conditions, other nitrogen oxides are in a gaseous state under normal conditions. As air pollutants, nitrogen oxides (NOx) often refer to NO and NO2. Under high-temperature combustion conditions, NOx mainly exists in the form of NO, with NO accounting for about 95% of the initially emitted NOx. However, NO is highly reactive with oxygen in the atmosphere to generate NO2, so NOx in the atmosphere generally exists in the form of NO2. NO and NO2 in the air reach equilibrium through photochemical reactions and mutual conversion. When the temperature is high or there are clouds and mist present, NO2 further reacts with water molecules to form the second important acid component in acid rain - nitric acid (HNO3). In the presence of a catalyst and with appropriate meteorological conditions, the rate of conversion of N02 to nitric acid is accelerated. Especially when NO2 and SO2 coexist, they can catalyze each other and form nitric acid at a faster rate.
