HA3LX: Maritime Methane Detection and Acoustic Imaging
In the maritime industry—especially onboard LNG/LPG carriers, gas‑fuelled vessels, and offshore terminals—gas leaks and mechanical faults present serious operational and safety risks. The complexity of cargo handling systems, the presence of high‑pressure lines, and the harsh offshore environment all demand tools that deliver absolute precision and reliability.
The HA3LX, the third‑generation handheld acoustic and methane laser camera from Hertzinno Technology Co., Ltd., is engineered specifically to meet those needs. Combining 144 digital MEMS microphones with a powerful TDLAS methane laser module, it gives crews an unprecedented ability to detect, visualize, verify, and quantify methane leaks—instantly and safely.
A Breakthrough for LNG/LPG and Dual-Fuel Vessels
Modern gas‑powered ships rely on tight safety controls. Even a small methane leak during bunkering, purging, or fuel gas supply operations can trigger alarms, delays, or—in the worst case—critical incidents.
The HA3LX provides maritime operators with capabilities designed for these exact scenarios:
🔍 Dual Detection: Acoustic + Laser Methane Verification
The device first uses its 144‑channel acoustic array to localize potential gas leaks, even in areas with high background noise such as compressors, manifolds, or engine rooms.
Once a leak source is identified acoustically, the integrated TDLAS methane laser sensor confirms and quantifies methane concentration from up to 30 meters away.
This is especially valuable during:
LNG bunkering operations
Cargo handling on gas carriers
Fuel gas supply system inspections
Engine room monitoring on dual-fuel vessels
Offshore platform pipeline surveillance
📏 Accurate Quantification for Compliance
The laser module measures methane from 0 to 50,000 ppm·m, with a response time of only 0.2 seconds.
This enables:
Instant severity assessments
More informed decisions during leak emergencies
Better reporting for Class, Port State Control, and ISM documentation
Built for Harsh Maritime Conditions
From Arctic LNG carriers to hot offshore loading terminals, equipment reliability is non‑negotiable. The HA3LX is designed to withstand maritime extremes:
🌧️ Built for the elements
IP54 protection
Operating temperatures from −20°C to +55°C
Suitable for high humidity environments (10–95% non‑condensing)
⚓ Explosion-Proof Safety
The HA3LX is ATEX certified, making it safe for use in explosive atmospheres found on:
LNG/LPG decks
Engine rooms
Fuel gas preparation rooms
Compressor stations
Offshore gas handling zones
🎥 High‑Resolution Optical Imaging
With a 13 MP optical camera, 4K photo resolution, and a 5‑inch touch display, operators can capture clear visual documentation of leak locations—even in tight or obstructed piping systems.
From Leak Detection to Full Acoustic Diagnostics
While methane detection is central, the HA3LX also brings significant value to maritime maintenance teams:
🛠 Multiple Inspection Modes
Leak Detection (gas & compressed air)
Mechanical Noise Analysis (bearings, valves, pumps)
Partial Discharge Detection (ideal for HV electrical rooms on LNG carriers or FPSOs)
This makes it a versatile tool for both deck and engineering teams during:
Planned maintenance
Dry-docking
Class surveys
Troubleshooting during vessel operations
Instant Reporting and Digital Workflow Integration
Documentation is a growing burden across the maritime sector. The HA3LX reduces workload with:
One‑click analysis
Auto‑generated inspection reports
On‑device annotations (text, voice, photos, tags)
Wireless export via Wi‑Fi, Bluetooth, or USB-C
These features streamline reporting for:
ISM safety systems
Class societies
PSC inspections
Internal maintenance records
Why Maritime Crews Prefer the HA3LX
Safer inspections with long‑distance, non‑contact measurement
Reduces downtime by pinpointing the exact leak source instantly
Supports rotating crews with repeatable, AI‑assisted diagnostics
Compact and lightweight (under 1.2 kg) for easy deck or engine‑room use
Includes spare battery, charger dock, and rugged carrying case for onboard operations
A Smarter Way Forward for Gas-Powered Shipping
As the maritime industry transitions toward cleaner fuels like LNG, LBG, and e‑methane, safety and precision in gas handling become even more critical. The HA3LX delivers a modern, data‑driven approach to gas leak detection—supporting safer operations, lower emissions, and smoother audits.
If you're looking to upgrade your vessel’s safety toolkit or streamline gas inspection processes, the HA3LX offers one of the most complete solutions available.
