OX-A431 Ozone + Nitrogen Dioxide sensor

OX-A431 Oxidising Gas Sensor Ozone + Nitrogen Dioxide:

The OX-A431 detects both ozone and nitrogen dioxide (O3 +NO2). The NO2-A43F measures only nitrogen dioxide, filtering out ozone. Using these sensors together allows you to calculate the O3 concentration by subtracting the corrected NO2-A43F concentration from the corrected OX-A431 concentration.OX-A431 O3 Sensor + NO2 Sensor price is available in sensotec website.
