Using the proven Chemiluminescence (CLD) measurement principle combined with the latest detector technology, the Ei400 NO/NO2/NOx Analyzer measures the reaction between nitric oxide and ozone to determine the nitric oxide concentration in gas. 


Incorporating a blue light LED or thermal converter into the sample path converts nitrogen dioxide into nitric oxide, thus allowing for the measurement of total nitrogen oxides (NOx) concentration.
