How SELMA Mini works

SELMA Mini utilizes TDLAS technology

TDLAS (Tunable Diode Laser Absorption Spectroscopy) is a technology that enables precise gas detection using a tunable diode laser. The laser emits a narrow beam of light at a wavelength that matches the absorption profile of the target gas. As the beam passes through the gas, some of the light is absorbed by its molecules. A sensor then captures the reflected light, and by analyzing how much was absorbed, the system determines the gas concentration.

Why leak detection matters

Continuous methane monitoring, especially in urban areas, is essential not only for safety but also for environmental protection. Methane is one of the most potent greenhouse gases, trapping heat much more efficiently than carbon dioxide. Even small leaks, if undetected, can increase and have a serious impact on the climate. This is why regular monitoring is important: it helps to detect leaks as soon as they occur, prevent dangerous situations and control emissions in accordance with environmental regulations.
