BL-CH4 Drone Methane Detector

The BL-CH4 is our flagship drone-mounted laser methane detection sensor, designed for lightweight and efficient deployment. Featuring an all-in-one integrated design, the BL-CH4 combines five essential modules: a laser receiver, laser indicator, laser emitter, RGB camera, and laser rangefinder. Its advanced sensor array, powered by intelligent algorithms, enables rapid detection and pinpointing of methane sources—allowing operators to identify leaks quickly and respond with timely action.

BL-CH4 Methane detector for drones
CH4 Assistant App

Wide-Area Coverage & High Efficiency

Drones can cover large and remote areas quickly, including pipelines, wellheads, landfills, and storage tanks.
Reduces time and manpower compared to ground-based inspections.

Real-Time, Non-Contact Detection

Equipped with laser or TDLAS (Tunable Diode Laser Absorption Spectroscopy) sensors for accurate, long-distance, non-contact gas detection.
Enables fast detection of methane leaks without the need for close physical access.

Enhanced Safety

Minimizes the need for personnel to enter hazardous or hard-to-reach environments (e.g., high-pressure zones, toxic gas areas).
Reduces exposure to risks like explosions, methane, H₂S, or oxygen-deficient zones.

High Accuracy & Sensitivity

Advanced sensors detect even trace levels of methane, with results often displayed in ppm·m (parts per million multiplied by distance).
Suitable for both localized leak detection and wide-area scanning.
