BLV BL-CH4 400 is designed as an advanced aerial methane-detection payload for operators who need faster and more precise long-range gas inspection. It combines TDLAS-based methane sensing with visible-light imaging and gimbal stabilisation, helping identify suspected leaks from up to 300 metres away. A key advantage of the 400 version is its improved sensitivity together with zoom-assisted visual confirmation, allowing operators to localise leak points more effectively. It is built for industrial methane inspection where stand-off distance, responsiveness, and visual confirmation all matter.

300 m Detection Distance

Long stand-off methane detection supports safer inspections and better access to hard-to-reach locations.

High-Precision Leak Location

TDLAS sensing with visual calibration helps crews identify leak points more accurately in the field.

IP55 Weatherproof Design

Rugged weather-resistant construction supports use in demanding industrial and outdoor environments.

5 ms Fast Response

Very fast response helps operators identify concentration changes quickly during active inspection work.

M350 And M400 Compatible

Designed for DJI Matrice 350 RTK and Matrice 400 platforms for more flexible enterprise deployment.

Enhanced Methane Inspection

Built for industrial methane detection where sensitivity, stand-off distance, and visual confirmation all matter.

Faster, clearer methane inspection

BL-CH4 400 is a high-sensitivity UAV methane detector designed for faster and more accurate stand-off inspection, helping operators identify and assess leaks from safer distances across industrial and environmental monitoring workflows.

300 m detection distance

The detector is designed for methane sensing from up to 300 metres away, helping crews inspect difficult or hazardous locations without getting too close to the source.

High-precision leak location

Public product materials highlight high-precision leak localisation, helping operators move from gas detection to clearer identification of the suspected leak point.

TDLAS methane sensing

The BL-CH4 400 is built on Tunable Diode Laser Absorption Spectroscopy, supporting precise airborne methane detection for professional inspection tasks.

Built for stronger stand-off inspection

The BL-CH4 400 is positioned not only as a gas sensor, but as a more capable inspection tool for teams that need distance, accuracy, and clearer field confirmation.

5 ms response speed

Very fast response helps operators identify methane concentration changes quickly during active inspection work.

Visual calibration support

Public descriptions state that visual calibration is combined with sensing support, helping crews confirm targets more effectively during flight.

Sharper field confirmation

The platform is designed to make methane inspection more actionable by giving teams better confidence when assessing suspicious areas from the air.

IP55 weatherproof design

Its IP55-rated construction supports use in demanding outdoor and industrial environments where weather resistance matters.

M350 and M400 compatibility

Current product pages list compatibility with DJI Matrice 350 RTK and Matrice 400, giving operators a practical route into larger-aircraft methane inspection.

Built for industrial environments

The BL-CH4 400 is positioned for industrial methane inspection where rugged deployment and dependable airborne sensing are both important.

Safer inspection distance

By allowing methane assessment from farther away, the detector helps reduce operator exposure around pipelines, facilities, and other monitored assets.

Enhanced methane workflows

The combination of stand-off sensing, faster response, and clearer localisation makes the BL-CH4 400 a stronger fit for recurring professional methane-inspection operations.
