Digital MEMS microphones for high-density acoustic imaging.

2kHz–150kHz

Wide frequency bandwidth for audible and ultrasonic inspection.

0.3–210m

Operating distance for close-range and long-distance inspection.

<1kg

Lightweight handheld design for field maintenance teams.
Applications

Where HA3 is used

HA3 is suitable for portable inspection tasks where engineers need to quickly find and document sound-based faults.

Power

Substation & Grid Inspection

Inspect partial discharge, corona and abnormal electrical sound sources in substations, switchgear and power assets.

Oil & Gas

Leak Inspection

Locate pressurized gas leaks, compressed air leaks and abnormal acoustic sources around valves, flanges and process units.

Data Center

Electrical Room Inspection

Inspect electrical cabinets, switchgear, cooling equipment and cable areas for abnormal acoustic sources.

Manufacturing

Plant Maintenance

Detect compressed air leaks, mechanical noise and abnormal sound sources in production and maintenance areas.

Heavy Industry

Equipment Troubleshooting

Inspect motors, fans, pumps, conveyors and rotating machinery in high-noise industrial environments.

Product Family

Acoustic Imaging Cameras

Compare HA3 with HA3T, HA3LX and fixed online acoustic cameras for different 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.

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 series acoustic camera 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.
HOW IT WORKS

01

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

02

Beamforming
AI beamforming algorithms suppress background noise and focus on target sound sources.

03

Visual Overlay
Acoustic heatmaps are displayed over HD optical images for intuitive source localization.

04

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

HA3 Acoustic Camera FAQ
why hertzinno acoustic camera with high performance

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 3.5-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.
