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.

Frequently Asked Questions

What is the BL-CH4 400 used for?

The BL-CH4 400 is a professional drone-mounted methane detection sensor designed for rapid, non-contact methane leak detection. It is ideal for inspecting natural gas pipelines, refineries, petrochemical facilities, landfills, oil and gas infrastructure, and other industrial sites where methane monitoring is critical.

Which DJI drones are compatible with the BL-CH4 400?

The BL-CH4 400 is designed for the DJI Matrice 350 RTK and DJI Matrice 400, providing seamless integration for enterprise inspection and environmental monitoring missions.

What detection technology does the BL-CH4 400 use?

The sensor utilizes TDLAS (Tunable Diode Laser Absorption Spectroscopy), an advanced laser-based methane detection technology that delivers highly accurate, selective, and reliable methane measurements while minimizing interference from other gases.

How far away can the BL-CH4 400 detect methane?

Depending on the model and environmental conditions, the BL-CH4 400 can detect methane leaks from distances of up to 300 metres, allowing operators to inspect hazardous or difficult-to-access areas without flying directly over the leak source.

How sensitive is the sensor?

The BL-CH4 400 offers a detection sensitivity of 1 ppm·m, enabling it to identify extremely small methane leaks for highly accurate inspections.

How quickly does the sensor respond?

The sensor features an ultra-fast 5 millisecond response time, allowing operators to identify methane leaks almost instantly while conducting aerial inspections.

Does the BL-CH4 400 include a camera?

Yes. The BL-CH4 400 includes a 13 MP visible-light camera with 4× optical zoom, allowing operators to visually inspect assets while simultaneously detecting methane leaks.

Can the BL-CH4 400 pinpoint the exact location of a methane leak?

Yes. The sensor combines laser methane detection with laser ranging and GPS positioning to accurately identify and record methane leak locations for reporting and maintenance planning.
