Abstract

PURPOSE:To precisely measure NOx concentration with cheap, light and small-sized apparatus, without affected by the influence of co-existing component in exhaust gas, by oxidizing NOx to NO2 with packed body of specific solid oxidizing agent and measuring NOx with the absorbance in the range of visible ray-ultraviolet ray.
