Nitrogen Oxides (NOX) Instruments:

Nitrogen Oxides (NOX) are composed of a group of seven compounds. Of those compounds, nitrogen dioxide (NO2) is the only one regulated by the U.S. EPA because of its prevalence in the atmosphere generated by manmade activities. Not only is NO2 a critical air pollutant, but it can also form ozone (O3) and acid rain as it reacts in the atmosphere. Additional nitrogen oxides include nitrous acid and nitric acid (NO).
