MEMBRAPOR has almost doubled the sensitivity of its highly selective NO2/CA-2 sensor for nitrogen dioxide (NO2) for use in air quality measurements to provide resolution of even lower concentrations in the ppb range. Membrapor has incorporated its proven catalytic ozone (O3) filter, thereby eradicating the otherwise usual O3 cross-sensitivity common to electrochemical NO2 sensors. Moreover, this advanced sensor can be used for measuring ranges of up to 20 ppm.
