1. A method for compensating a temperature gradient effect for gas concentration sensors, the method comprising:
variating a temperature gradient;
measuring a variation of gas concentration depending on the variation of the temperature gradient;
analysing a dependence of the gas concentration and the temperature gradient for setting up an error correction function; and
applying the error correction function to correct measured values of the gas concentration.
