Applications

Where HA3LX is used

HA3LX is suitable for field inspection tasks where engineers need to locate acoustic leak sources and verify methane concentration in one workflow.

Oil & Gas

Facility Leak Inspection

Locate acoustic leak sources and verify methane concentration around valves, flanges, compressors, tanks and process equipment.

Chemical

Chemical Plant Safety

Support gas leak inspection and acoustic fault localization in complex industrial environments with methane verification capability.

LNG & Gas

LNG & Gas Handling Sites

Inspect LNG terminals, gas preparation rooms, compressor stations and high-pressure gas handling areas for methane-related risks.

Pipeline

Pipeline & Valve Stations

Detect ultrasonic leak sources and verify CH₄ concentration around pipeline equipment, valve stations and gas transmission assets.

LDAR

LDAR Inspection

Support leak detection and repair workflows with acoustic localization, methane concentration evidence and inspection documentation.

Product Family

Acoustic Imaging Cameras

Compare HA3LX with HA3, HA3T and fixed online acoustic cameras for acoustic, thermal, methane and online monitoring workflows.

From leak sound to methane verification.

HA3LX combines acoustic imaging with TDLAS methane laser detection. The microphone array first visualizes the ultrasonic sound source from a suspected leak. The methane laser sensor then verifies CH₄ concentration at the target area, helping inspectors confirm whether the acoustic source is methane-related and document the inspection result.
HOW IT WORKS

01

Sound Capture
144 digital MEMS microphones capture audible and ultrasonic sound signals from the target area.

02

Acoustic Localization
Beamforming algorithms locate the suspected leak source and display it as an acoustic heatmap.

03

Methane Verification
The TDLAS methane laser sensor measures CH₄ concentration in real time without direct contact.

04

Inspection Output
Engineers can capture images, videos, annotations and inspection records for maintenance reporting.

FAQ of HA3LX Acoustic Cameras
The first acoustic camera with TDLAS technology for Nature gas leak detection and concentration measurement

What is HA3LX used for?

HA3LX is used for methane leak inspection, gas leak localization, LDAR inspection and acoustic fault detection in oil, gas, chemical, LNG and industrial facilities.

What is the difference between HA3 and HA3LX?

HA3 is designed for general acoustic imaging inspection. HA3LX adds a TDLAS methane laser sensor, allowing inspectors to verify CH₄ concentration after locating a suspected leak source acoustically.

How does HA3LX detect methane?

HA3LX uses Tunable Diode Laser Absorption Spectroscopy to measure methane concentration along the laser path. This enables non-contact methane verification after acoustic leak localization.

Is HA3LX suitable for LDAR inspection?

Yes. HA3LX supports LDAR workflows by combining acoustic leak localization with methane concentration verification and inspection documentation.

Can HA3LX detect non-methane leaks?

Yes, The acoustic imaging function can locate ultrasonic sound generated by pressurized gas leaks, but the TDLAS methane sensor is specifically used for CH₄ verification. For non-methane gases, the acoustic result shows leaks.
