The LMm (Laser Methane mini) is designed to remotely detect methane, as well as other gas mixtures containing methane (natural gas or similar gases). It allows to quickly and safely find the point of gas leakage by pointing the laser beam at the studied area.

LMm advantages
Convenient for regular inspections
Ideal for Outdoor Use
Easily spot the measuring point — even under strong outdoor sunlight with the green laser pointer's excellent visibility.
Intrinsically Safe
LMm utilize the green laser pointer, and can be used in the following areas: Zones 1 and 2 for city gas, coal mines and other hazardous areas.
Compact Design
Superior portability for its small size with a long-lasting battery. Pocketable for work clothes and convenient for carrying.
High Durability
Solid, dust-proof and splash-proof construction for use in harsh environments. Easily maneuverable — even in cramped places or on a ladder.
Connection with Android Devices
Wireless communication is enabled when an exclusive application is installed on an Android device (SA3C32A-BEonly).
Handheld Grip
This handle for the Laser Methane mini is the ideal accessory to make long walking surveys more comfortable (optional).
How It Works?
The measurement principle of this equipment uses the characteristics of methane, which absorbs the laser beam (infrared rays) of a specific wavelength (infrared absorption technology). The laser beam directed at targets such as gas piping, the ground, overhead pipe, etc., will reflect back a diffused beam from the target. The device will receive the reflected beam and will measure the absorptivity of the beam, which will then be calculated into methane column density (ppm-m).

Not yet. The iOS app release is scheduled for 2020.
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.
No, since this device modification does not provide for recording or transfer of inspection data. The quadcopter version also has an increased detection range.
