SELMA Dome G5
New generation vehicle-mounted remote laser methane detector
Remote detection of methane leaks at a distance of up to 1 km
Introducing SELMA Dome G5, our latest vehicle-mounted remote laser methane detector. Designed for mobile inspections, it detects gas leaks up to 1000 meters away with an eye-safe laser that is harmless to humans and animals. Just mount it on the roof of your car or truck and begin your survey. For even greater efficiency, SELMA Dome G5 can be paired with SELMA MPB laser sniffer, which increases sensitivity and provides full control over the inspection route.

How SELMA Dome G5 works
SELMA Dome G5 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.
