ABSTRACT:
A device for detecting at least one gas with an absorption band in the infrared range. The device includes a cell containing a gas mixture to be tested, an infrared radiation source, a power supply circuit for the source, an infrared radiation sensor and a signal processing line connected to the output of the sensor. The cell is compact and the radiation source and the radiation sensor are held in direct contact with the gas mixture therein.
