BL-CH4 400
Drone-based Methane Detection Sensor
For DJI M350/400
The BL-CH4 400 is a light-weight, high-sensitivity gas detector based on Tunable Dlode Laser Absorption Spectroscopy (TDLAS),which enables rapid identification of methane from up to 300m away, or at a concentration as low as 5ppm. m. 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 stabillzation 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.
