LM-100
Handheld, explosion-proof laser methane detector with a range of up to 100 m
Convenient Handheld Inspections at Extended Range
Sometimes inspections require a tool that is both powerful and portable, especially when detecting methane or natural gas leaks in the field. The LM-100 meets this need. It detects methane from up to 100 meters away using reliable TDLAS technology, allowing operators to inspect hard-to-reach areas without approaching the source. The device is explosion-proof and supports Bluetooth data logging and transfer. With its long detection range and user-friendly operation, the LM-100 helps teams work safely and efficiently during routine and emergency inspections.

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 LM-100 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.
