Zusammenfassung:— The article is devoted to the study of a methane leak detector based on absorption spectroscopy. An LED matrix with a wavelength of ~3.3 μm was used as a radiation source, where one of the methane absorption lines is located. The system is temperature stabilized. A threshold sensitivity of approximately 60 ppm CH 4 was obtained.
