BLV BL-CH4 MINI 3 PRO is designed as a compact methane-detection payload for DJI Dock 3 operations and the Matrice 4D/4TD platform. It combines TDLAS-based sensing with a lightweight dock-ready design to support Intelligent methane detection and mapping across industrial sites and pipeline infrastructure. Compared with earlier dock-based versions, it extends effective detection distance while maintaining compact size and low power consumption. It is especially well suited to recurring unmanned inspections where automation, compact integration, and efficient methane detection are priorities.
Key features
- Dock 3 Integration Purpose-built for DJI Dock 3 and Matrice 4D or 4TD workflows to support recurring autonomous methane inspections.
- TDLAS Methane Detection Uses Tunable Diode Laser Absorption Spectroscopy for precise methane detection and concentration mapping.
- 20 ms Response Time Fast response helps operators identify methane events quickly during automated or supervised inspection missions.
- Lightweight Payload Compact 240 g design helps preserve aircraft efficiency and suits smaller dock-based platforms.
- Up To 70 m Detection Stand-off methane sensing supports safer inspection of industrial sites and pipeline infrastructure.
- Intelligent Inspection Ready Designed for compact, repeatable unmanned methane monitoring where automation and low operational overhead matter.
Compact methane sensing for Dock 3
BL-CH4 MINI 3 Pro is a compact UAV methane detection sensor built for DJI Dock 3 workflows, combining TDLAS-based sensing, low weight, and direct Matrice 4D/4TD compatibility for recurring remote inspections on industrial sites and pipelines.
DJI Dock 3 integration
The sensor is designed specifically for DJI Dock 3 and is listed as compatible with Matrice 4D and 4TD aircraft, making it suitable for repeat remote methane-monitoring missions.
TDLAS methane detection
It uses Tunable Diode Laser Absorption Spectroscopy to detect and map methane concentrations with high precision and accuracy during flight missions.
Compact 240 g payload
At 240 g including the gimbal, the payload is built to preserve aircraft efficiency while still adding practical methane-detection capability.
Built for recurring remote inspections
BLV positions the MINI 3 Pro as a practical tool for unmanned industrial-site and pipeline inspections where compact size, automation readiness, and lower operating cost matter.
Up to 70 m detection
The product page lists detection distance from 1 to 70 metres depending on reflector and conditions, supporting safer stand-off inspection.
20 ms response time
A 20 ms response time helps operators identify methane events quickly during remote or supervised inspection missions.
Clearer field assessment
By combining stand-off sensing with compact dock-based deployment, the payload helps teams assess suspected methane issues more efficiently across industrial assets.
5 ppm·m sensitivity
The listed sensitivity of 5 ppm·m helps the sensor detect relatively low methane concentrations in professional inspection workflows.
E-Port and 2-axis gimbal
The specifications list an E-Port interface and 2-axis stability enhancement in pitch and roll for cleaner aircraft integration and steadier sensing.
Designed for smaller dock ecosystems
The MINI 3 Pro is framed around low power draw and compact form, making it a more practical fit for Dock 3 aircraft than larger methane payloads.
IP55 protection
The specification sheet lists IP55 protection, supporting more dependable outdoor use in professional industrial environments.
Industrial application range
BLV lists pipeline leakage detection, refinery detection, offshore gas detection, chemical plant inspection, landfill inspection, and fire warning among the main application scenarios.
