BL-CH4 400: Drone-based Methane Detection Sensor for DJI M350/M400
The BL-CH4 400 is a light-weight, high-sensitivity gas detector based on Tunable Diode Laser Absorption Spectroscopy (TDLAS), which enables rapid identification of methane from up to 300 m away. The device cleverly combines the detection laser with the precise calibration of the visible light sensor to achieve accurate visual inspection; cooperating with the intelligent stabilization control technology of the gimbal, it can quickly provide users with crucial information to help users grasp the opportunity, and improve the perception ability and operation efficiency to a new level.
Key performance
Equipped with a professional surveying and mapping lens, BL-CH4 400 has extraordinary performance during flight mission.
- 300 m telemetry distance (300 m version)
- 5 ms response speed
- Precise location of leak point
- Monitoring data is sent to the cloud in real time
Two versions: 300 m and 150 m detection range. Both share the same airframe, gimbal, camera and laser rangefinder.
