摘要： The invention relates to a method for determining an NO
x concentration in a measurement gas, wherein a measurement value for the NO
x concentration is determined from the sensor signal of a gas sensor and wherein a measurement value for the concentration of a second component in the measurement gas is determined, wherein a corrected value for the NO
x in the measurement gas is determined from the measurement values, and wherein the measurement value and the corrected measurement value for the NO
x concentration are displayed and/or output (Fig. 1).
