摘要：
The invention concerns a method and a sensor for measuring gas concentrations. The sensor according to the invention comprises an element (A1, 5) which is sensitive to a chemical reaction of the gas being measured and means for measuring (13) the temperature of the element (A1, 5) sensitive to a chemical reaction of the gas being measured. According to the invention, the temperature-measuring means (TP1, TP2) are constituted by several series-connected thermopairs (13).
