Abrégé

The invention relates to a method for verifying a calibration of an ultrasonic spirometer, the method comprising determining an actual value of a distance between a first ultrasonic transducer and a second ultrasonic transducer of a spirometer, determining a difference between the actual value of the distance and a nominal value of the distance that is assigned to the spirometer, and accepting an actual calibration of the spirometer if an absolute value of the difference is smaller than or equal to a first threshold value, or refusing the actual calibration of the spirometer if the absolute value of the difference is bigger than the first threshold value, wherein the first threshold value is 5% of the nominal value of the distance. The invention further relates to a spirometer that is adapted to carry out this method as well as to a method for calibrating a spirometer.

Abrégé

The invention describes a method that is used to determine the linearization curve of a sensor for specific gas components by combining this sensor with an ultrasonic molar mass sensor. The described method uses the fact that the molar mass sensor exhibits a completely linear response when two gas compositions of differing molar mass values are mixed. Using this feature a non linear-response of a sensor for specific gas components can be determined and a linearization curve can be computed.
