Hereafter we present a laboratory evaluation of commercially available amperometric sensors for the monitoring of O3 and NO2 in ambient air at ppb level. The tests includes the determination of the response time of sensors, their calibration function, the evaluations of repeatability, short and long term drifts, the hysteresis effect and the matrix effect. Interferences from gaseous compounds, temperature and humidity parameters are also evaluated.
