The ented (and ent pending) Alphasense solution is to combine the Nitrogen Dioxide (NO2B43F or NO2A43F) and oxidising gas (OXB431 or OXA431) sensors as a pair: the NO2 sensor measures only NO2 and the difference between the two sensors gives the Ozone concentration.

sensor system). Clearly, the Alphasense NO 2sensors systematically show the lowest standard deviations ( µg/m3, when averaged over the entire experiment) and relatively small differences between sensors. Next ‘best’ are the Membrapor 1 ( µg/m3) and Membrapor C20 ( µg/m3) while the Cairclip systems indicate a much higher value ( µg/m3 and more variability between copies. y ...

Alphasense IRCA sensors use the principle of NonDispersive InfraRed (NDIR) to determine gas concentration. Each sensor consists of an infrared source, optical cavity, dual channel detector and internal thermistor. Gas diffuses into the optical cavity. Light from the infrared source passes through the optical cavity where it interacts with the gas before impinging on the detector. Certain ...
