LPD-20M
Small and robust remote laser methane detector with a range of up to 20 m
Find methane leaks from up to 20 meters
If you're looking for a compact yet powerful methane detector for harsh environments, the LPD-20M is an ideal choice. Its IP66 rating allows reliable operation in dusty and wet conditions, while its 5 ppm×m sensitivity, enabled by modern TDLAS technology, ensures accurate leak detection results. This makes the LPD-20M well-suited for natural gas facilities where reliability and precision are critical.

Fast response and large measurement range
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.
The LPD-20M uses TDLAS (Tunable Diode Laser Absorption Spectroscopy) technology to provide precise methane detection with a tunable diode laser. The laser emits a narrow beam of light at a wavelength that matches methane’s absorption profile. As the beam passes through the gas, some of the light is absorbed by the molecules. A sensor then captures the reflected light, and by analyzing how much is absorbed, the system calculates the methane concentration.

Why leak detection matters
Methane monitoring, especially in urban areas, is essential not just for safety, but also for protecting the environment. Methane is a potent greenhouse gas, trapping heat much more effectively than carbon dioxide. Even small leaks, if left undetected, can grow and seriously impact the climate. Regular monitoring helps detect leaks early, 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.
Yes, because glass transmits the near infrared radiation well.
