Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a photometer which enables the measurement of multiple components with a high degree of accuracy and a minimum possible apparatus outlay. SOLUTION: In the photometer for measuring gas components which has an infrared radiation source with radiation emitter modulation, a measuring cell provided with a measurement/comparison chamber, and a detector filled with a gas component X, at least another detector is placed downstream of the detector filled with the gas component X in order to measure two or more components. For measuring another gas component, the other detector is filled with the isotope component of the other gas component, and the detector filled with the gas component X is optically transparent with respect to the isotope component of the other gas component or the characteristic absorption band of the other gas component.
