HA3 handheld acoustic camera for field inspection.
HA3 is a handheld acoustic imaging camera designed for industrial inspection. It uses a 144-channel MEMS microphone array and AI beamforming algorithms to visualize ultrasonic sound sources and help engineers locate gas leaks, partial discharge and abnormal mechanical noise. It is suitable for power, oil and gas, manufacturing, data center and heavy industry inspection workflows.
What HA3 helps engineers detect
HA3 turns invisible sound sources into visible acoustic heatmaps, helping maintenance teams find faults that are difficult to confirm by human hearing, visual inspection or periodic checks alone.
Gas Leak Localization
Locate pressurized gas and compressed air leaks by visualizing ultrasonic leak emissions on screen.
Partial Discharge Inspection
Detect corona, tracking and partial discharge sound sources in substations, switchgear and electrical assets.
Mechanical Fault Diagnosis
Identify abnormal sound from motors, bearings, pumps, fans and rotating equipment during field inspection.
On-device Analysis
Process acoustic images and inspection data directly on the device for fast field decision-making.
From ultrasonic sound to visual inspection evidence.
HA3 combines a high-density MEMS microphone array, beamforming algorithms and optical image overlay. The camera captures sound arrival differences, calculates the sound source direction and displays the result as an acoustic heatmap over the visual image.
Where HA3 is used
HA3 is suitable for portable inspection tasks where engineers need to quickly find and document sound-based faults.
Substation & Grid Inspection
Inspect partial discharge, corona and abnormal electrical sound sources in substations, switchgear and power assets.
Oil & GasLeak Inspection
Locate pressurized gas leaks, compressed air leaks and abnormal acoustic sources around valves, flanges and process units.
Data CenterElectrical Room Inspection
Inspect electrical cabinets, switchgear, cooling equipment and cable areas for abnormal acoustic sources.
ManufacturingPlant Maintenance
Detect compressed air leaks, mechanical noise and abnormal sound sources in production and maintenance areas.
Heavy IndustryEquipment Troubleshooting

HA3 Acoustic Camera FAQ
What is HA3 used for?
HA3 is used for handheld acoustic inspection, including gas leak localization, partial discharge detection, compressed air leak detection and mechanical fault inspection in industrial environments.
What makes HA3 different from a standard ultrasonic detector?
HA3 uses a 144-channel microphone array to visualize sound sources as an acoustic heatmap, helping engineers see the location of leaks or discharge rather than only hearing a signal.
Can HA3 detect partial discharge?
Yes. HA3 is designed for partial discharge inspection and can help locate corona, tracking and discharge-related ultrasonic sound sources in substations, switchgear and electrical assets.
Can HA3 be used for a full inspection shift?
HA3 uses rechargeable Li-ion batteries and supports battery replacement. The product specification lists a minimum 7-hour battery life per charge cycle, supporting extended field inspection workflows.
What is the difference between HA3 and HA3LX?
HA3 is designed for general acoustic inspection. HA3LX adds methane laser detection capability for oil, gas and chemical environments where methane verification is required.
