The production of all sensors is subject to manufacturing-related variations - for example, the electro-chemical sensors we also use, such as nitrogen dioxide, sulfur dioxide and ozone. We therefore only use sensors from manufacturers who provide us with individual calibration data for each sensor. This is the only way to ensure accuracy.
In addition, we perform an additional base-line calibration prior to shipment of each instrument.
In the smartphone app, there is the option to perform the baseline calibration yourself at home. Furthermore, the air-Q has an automatic drift correction.
For cost reasons, we do not send individual calibration certificates.
