Abstract
The article presents the zero-offset calibration procedure of the Alphasense NO2-B43F sensor, which is intended for cyclical correction of results during the operation of the sensor in the measurement of low concentrations of NO2 in the atmospheric air. The procedure uses the correlation method of temperature drift correction of the zero-offset, which is based on a statistical analysis of a long-term series of measurements and reference indications from a certified air pollution measurement station.
