Laser Methane mini

The Laser Methane mini (SA3C32A) and Laser Methane mini-G (SA3C50A) are laser-type detectors, capable of safely and quickly detecting gas leaks from a distance. The Laser Methane mini-G guarantees best visibility through green laser and capable to communicate with mobile devices! By linking to an Android device, you can view your recordings as a graph, the measurement history and measured locations on a map.


Principle of measurement
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, 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).


LMm-G SA3C50A is ideal for outdoor use
Ideal for outdoor use (LMm-G – SA3C50A)
Easily spot sight of a measuring point even under strong outdoor sunlight with the green laser pointer’s excellent visibility. With the inclusion of an organic electroluminescence display, measurement values are clearly displayed too. In addition, when detecting methane gas, Laser Methane mini-G indicates this with a flashing super- luminosity LED and buzzer.


SA3C50A LMm-G with Android App
Connection with Android devices (LMm-G – SA3C50A)
Wireless communication is enabled when an exclusive application is installed on an Android device, which can then record the values measured by Laser Methane mini-G. Also, in conjunction with the GPS function on the Android device you can view the measurement history and the measured locations on the map.


Intrinsically Safe model SA3C32A LMm
Intrinsically Safe (LMm – SA3C32A)
Can be used in the following hazardous areas Zones 2 and 2 for city gas, coal mines and etc.



High durability and compact design
Solid, dust-proof and drip-proof construction for use in harsh environments. Superior portability for its small size with a long-lasting battery. Pocketable for work clothes and convenient for carrying. You can work easily with Laser Methane mini-G even in cramped places or on a ladder. Continuous operation time over five hours: sufficient for performing a full day’s work.
