Laboratory and in-situ validation of ozone microsensors, αSense, model B4 O3 sensors : Task 4.3: Testing protocol, procedures and testing of performances of sensors (JRC, MIKES, INRIM, REG-Researcher (CSIC))

The aim of this report was to evaluate and validate O3-B4 sensors of Sense Inc. (UK) with laboratory and field tests under ambient air conditions corresponding to a specific micro-environment: background station, rural areas. This report presents the evaluation of the performances and determination of the laboratory measurement uncertainty of the sensor values, compared to uncertainties fixed by the Data Quality Objective (DQO) of the European Air Quality Directive for indicative methods.
