Ambient air monitoring is a key focus of Membrapor’s research and development efforts. After intensive work over several years, Membrapor is proud to present a NO2 sensor without O3 cross sensitivity. The brand new NO2/CA-2 is designed for NO2 air quality measurements in the ppb range and is equipped with a filter that filters out O3. The typical O3 cross sensitivity of electrochemical NO2 sensors is thus eliminated and highly selective measurements of NO2 possible. Due to the catalytic nature of the filtering process, the NO2/CA-2 enables reliable, selective NO2 detection over several years. Check out the data sheet for more details.
