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.

144

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.

FAQ
Why Acoustic & Thermal

What is the benefit of the HA3T's dual-sensor technology?

A: The HA3T combines acoustic imaging with thermal imaging, allowing maintenance teams to verify faults using two physical phenomena: sound (e.g., friction, turbulence) and heat (e.g., overheating components). This dual-verification significantly reduces false positives in mechanical and electrical inspections.

What is the thermal resolution of the HERTZINNO HA3T?

The HA3T features a high-performance uncooled vanadium oxide thermal sensor with a resolution of 640 × 512 pixels, providing crisp thermal images that are superior to many standard industrial thermal cameras.

Can HA3T detect partial discharge?

Yes, the HA3T is highly effective for Partial Discharge (PD) detection on high-voltage equipment. It not only locates the PD sound source but can also identify associated hotspots caused by electrical stress, ensuring comprehensive diagnosis.

Why is the HA3T's integrated thermal sensor better than modular attachments?

The HA3T's integrated design eliminates the risk of broken connectors or lost modules common with external attachments. It provides higher Ingress Protection (IP54) against dust and water, ensuring a longer operational lifespan. Additionally, the integrated sensors are factory-calibrated for perfect alignment, removing the need for manual parallax correction in the field.

Does the HA3T require assembly or calibration before use?

No. Thanks to its all-in-one architecture, the HA3T is ready to use instantly. The 144 microphones and the thermal lens work in perfect sync out of the box, offering maximum convenience for maintenance teams.
