A method for the calibration of a sensor system is provided, the method including use of two calibration media. A high-quality first calibration medium, having a standardized reference independent of the sensor system to be calibrated, is used for a first calibration step in which the sensor system is calibrated and adjusted. A second calibration step immediately follows using a second calibration medium, having a non-standardized reference and being a component of the sensor system, to generate and store measuring signals of the second calibration medium with at least one sensor of the sensor system. Upon subsequent calibrations of the sensor system the second calibration medium is used exclusively so as to generate measuring signals of the second calibration medium with the sensor. If the measuring signals generated in the subsequent calibrations deviate from the stored measuring signals of the second calibration step, an adjustment of the sensor is effected.
