Cofem SDN Nitrogen Dioxide (NO2) Diffusion Sensor

SDN is a nitrogen dioxide (NO2) diffusion sensor for the COsensor system. It is designed according to EN 50545-1 European standard and is certified to UNE 23300. It works with all conventional (CCO, MiniCO) and other COsensor control panel models. NO2 is a major component of diesel vehicle exhaust; measuring only CO is insufficient in parking areas with heavy diesel traffic.
