Based on DJI payload SDK, the DJI M300 laser methane gas leakage detector is an extremely sensitive gas detection sensor for drones, based on Tunable Diode Laser Absorption Spectroscopy (TDLAS). It allows you to very quickly identify methane leaks from up to 80m away or at concentrations as low as 5ppm.m. Powered by DJI SkyPort, the methane gas detector can be seamlessly integrated with the DJI Matrice 200 V2, DJI M300, and DJI M350 drones.


Gas pipeline inspection

During the inspection process, inspection status (including UAV status, telemeter status, and methane measurement results) can be viewed in real-time. In case of pipeline leakage, the terminal equipment will automatically sound and light an alarm and record data (time, coordinates, leakage concentration, on-site photos) to automatically generate inspection reports later.


Residential building gas leak detection, manual flight, and automatic flight detection for residential buildings

The CH-4 drone laser methane telemeter only needs 0.1S to complete detection of natural gas leaks at the target point. During the inspection process, the M300 drone does not need to stop and displays the gas concentration in the current household’s kitchen in real-time.


Gas station inspection, frame selection of the station area, and automatic production of inspection routes

The CH-4 drone laser methane telemeter can also be used for methane leakage monitoring in landfills and methane leakage detection before LNG carriers enter ports. After the inspection is completed, the leak point is automatically marked and the user can click the icon to view the detailed information.
