BL-CH4 400

BL-CH4 400 UAV Laser Methane Leak Detector

High-Sensitivity Long-Range Methane Detection from the Air

The BL-CH4 400 methane detector is a lightweight, high-performance payload designed for advanced aerial methane leak detection across oil and gas, utilities, landfills, and industrial environments. Built on TDLAS (Tunable Diode Laser Absorption Spectroscopy) technology, the BL-CH4 400 detects methane leaks from distances of up to 300 meters with ultra-high sensitivity down to 1 ppm·m — without interrupting operations on the ground.

Combined with a 113MP RGB camera and 4× optical zoom, operators gain precise leak identification and high-resolution visual confirmation in a single flight. Real-time coordinate tracking, cloud-based data transmission, and intelligent gimbal stabilization make the BL-CH4 400 methane detector a powerful tool for efficient, scalable aerial methane monitoring.
