BL-CH4 400 UAV Laser Methane Leak Detector

High-Sensitivity Long-Range Methane Detection from the Air

The BL-CH4 400 UAV Laser Methane Leak Detector is a lightweight, high-performance methane detection payload designed for advanced aerial inspections across oil & gas, utilities, landfills, and industrial environments.

Built on TDLAS (Tunable Diode Laser Absorption Spectroscopy) technology, the BL-CH4 400 enables rapid, non-contact methane leak detection from distances of up to 300 meters, while achieving ultra-high sensitivity down to 1 ppm·m. Combined with a 113 MP RGB camera and 4× optical zoom, operators gain both 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 a powerful tool for efficient, scalable methane monitoring without interrupting operations.
