A measuring device for sensing different gases and gas concentrations, includes an infrared radiation source, a measurement channel, which has an optical path and a gas interaction path, and radiation detectors arranged along the measurement channel. The optical path has a first band-pass interference filter arranged at a first deflection point and a first radiation detector is arranged after the band-pass interference filter. A method that uses the measuring device, includes: measurement radiation is introduced into the measurement channel containing the gas to be measured, the measurement radiation hits the first band-pass interference filter, wherein only radiation of a wavelength defined by the first band-pass interference filter hits the first radiation detector, radiation reflected at the band-pass interference filter is forwarded along the optical path in the measurement channel to a second radiation detector, and the gas concentrations measured by the radiation detectors are evaluated.
