BL-CH4 Mini 3 Pro

UAV-Based TDLAS Methane Detection Sensor for DJI Dock 3

Dock-Ready Methane Detection for Fully Autonomous Operations

The BL-CH4 Mini 3 Pro is a compact, high-precision UAV-based methane detection sensor purpose-built for DJI Dock 3 and next-generation autonomous drone workflows.

Powered by TDLAS (Tunable Diode Laser Absorption Spectroscopy) technology, the BL-CH4 Mini 3 Pro delivers reliable methane detection with 5 ppm·m sensitivity, fast 20 ms response time, and detection distances of up to 70 meters, all in a lightweight payload optimized for frequent, unattended inspections.

Seamlessly integrated with DJI Dock 3, DJI Matrice 4D / 4TD, and DJI FlightHub 2, the BL-CH4 Mini 3 Pro enables scalable methane monitoring across pipelines, industrial facilities, landfills, and environmental monitoring sites—without requiring on-site pilots.
