SELMA Dome
Vehicle mounted remote laser methane detector for monitoring methane in ambient air
Fast and efficient natural gas leak detection in urban and suburban environment
SELMA Dome is designed for easy and accurate detection of methane in ambient air. Just mount it on your vehicle’s roof and follow your route — the system identifies gas leaks at distances of up to 80 meters. Eye-safe laser enables inspections without harming humans and animals. For enhanced sensitivity, SELMA Dome can be paired with SELMA MPB laser sniffer.

How SELMA Dome works
SELMA Dome 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.
FAQ
Honest answers to important questions
No, each device is designed to detect a specific gas. This provides a 100% probability of leak detection of methane and not any other gas.
Laser radiation is completely safe, it corresponds to class 1.
Yes, the instrument works in all weather conditions.
No, there is no impact.
No. The detector contains a reference cell with methane inside and calibration is performed at each start-up and during operation.
It works remotely. There is no direct contact with the hazardous environment.
