Measurement of Nitrogen Dioxide
For measuring nitrogen dioxide concentration in ambient air the chemiluminesence method is used primarly.Nitrongen dioxide concentrationas are determined indirectly from the difference between the NO and NOX concentrations in the atmosphere.These concentrations are determined by measuring tje light emitted from the chemiluminesece reaction of NO with O3 and the light output is proportional to NO present in the ambient air stream.
Reaction in the Atmosphere
NO is a colorless gas that has some harmful effects on human health , but these effects are substantially less than those of an equivalent of Nitrogen Dioxide.In the atmosphere NO reacts with O2 to form nitrogen dioxide , a brown- coloured gas that is a serious repspiartory irritant.Its brown color is strong enoughtaht is often possible to see a distinct brown colr emerging from a power plant stack or from the vent of any process using nitric acid,which realese NO2.

Good to learn about the hazards in the environment.If NO is produced by factories then there has to be a check because little as it may sounds...adds up to a lot of decay and damage of health.

A lot of the time the information is not legible or missing on older equipment. During the course of the previous owner, he probably used an concrobium fogger to replace the outdoor system.
