Abstract:
A method for determining an NOx concentration in a measurement gas is provided, where a measurement value for the NOx concentration is determined from the sensor signal of a gas sensor and a measurement value for the concentration of a second component in the measurement gas is determined. A corrected value for the NOx in the measurement gas is determined from the measurement values, and the measurement value and the corrected measurement value for the NOx concentration are displayed and/or output.
