AIRINS Sniffer4D Nano 2 Plus Multi-Pass TDLAS Methane Unit

Sniffer4D Nano 2 Plus Methane Unit: Detect Natural Gas Leaks with Multi-Pass TDLAS Precision

The Sniffer4D Nano 2 Plus Methane Unit is a standalone gas detection payload built for the DJI Matrice 4 series and DJI Dock 3, using Multi-Pass Tunable Diode Laser Absorption Spectroscopy to sense methane with a 200 ppb limit of detection. Unlike the Multi-Gas Base Unit's five module slots, this is a dedicated single purpose sensor built specifically for methane screening, with no other gas modules installed alongside it.

Built for pipeline operators, landfill managers, and natural gas facility inspectors running routine CH4 screening flights, the unit uses contact based sampling through an intake tube, measuring concentration directly inside its gas chamber during flight rather than sensing remotely.

The same compact housing as the Base Unit, weighing roughly 8.5 ounces (240 grams), mounts natively to the Matrice 4D and 4TD E-Port, with integration kits available for the Matrice 400 and Matrice 4E and 4T.

Key Features and Benefits

• MP-TDLAS detection: senses methane with high gas selectivity and precision.
• 200 ppb detection limit: catches low level methane leaks early.
• 11,000 ppm linear range: covers trace leaks to high concentrations.
• One second response: delivers real time readings during active flight.
• Standalone design: dedicated methane sensing without other gas modules installed.
• IP55 rating: operates safely in wet, dusty field conditions reliably.
• Contact based sampling: draws air through a dedicated intake tube.
• Encrypted data retrieval: stores twelve hours of mission data offline.
• Onboard 32GB storage: retains complete mission logs in CSV format.
• AIRINS.ai integration: processes flight data into structured methane leak reports.

Precision Screening for Gas Programs

Precision screening starts with a sensor built for one gas only. The MP-TDLAS module offers gas selectivity sensitive only to methane, with repeatability under 1 percent FS and resolution roughly 100 times finer than AIRINS' standard NDIR methane module. Encrypted transmission runs at 1Hz, and a twelve hour retrieval buffer protects mission data if cellular signal drops mid flight. The onboard 32GB card backs up every reading locally, so a single flight produces a defensible dataset without follow up sampling. That combination of selectivity and data integrity means fewer false positives and fewer repeat site visits.

Compatibility and System Integration

• Matrice 4D/4TD (hardware included): connects to the aircraft's E-Port, Dock 3 ready.
• Matrice 400 Integration Kit (sold separately): mounts unit with 50cm sampling tube.
• Matrice 4E/4T Integration Kit (sold separately): mounts unit with 25cm sampling tube.
• DJI Pilot 2 (included with remote controller): displays live methane concentration readings.
• DJI FlightHub 2 (third party software): enables remote monitoring and payload control.
• AIRINS.ai platform (included, perpetual license): converts flight data into structured leak reports.

Applications and Use Cases

• Natural gas facility screening: detect leaks across pipelines and infrastructure.
• Landfill routine surveys: monitor methane emissions across active waste sites.
• Pipeline right-of-way inspection: screen for leaks along buried gas lines.
• Oil and gas compliance: document methane concentration for regulatory reporting.
• Wellhead and facility monitoring: check for fugitive methane emissions regularly.
• Preliminary leak screening: identify anomalies before ground crews follow up.

The Sniffer4D Nano 2 Plus Methane Unit exists to give gas programs a fast, repeatable way to screen for methane leaks from the air before committing ground crews. By pairing laser based selectivity with a lightweight airborne platform, it turns routine CH4 surveys into a faster, more consistent process.
