The Series 1 acoustic camera is our single-modality imaging device, offered in varying sensitivities and application ranges. The HZ-HA-171P serves as the entry-level model, detecting partial discharges, gas leaks, and mechanical anomalies with ultra-low power consumption (7-hour battery operation). Equipped with AI analytics, it classifies discharge types, estimates leak volumes/costs, and performs four mechanical parameter detection modes. This versatile solution suits power industry inspections, compressed gas leak detection, and seal integrity testing.
The HZ-HA-170P features ATEX certification (II 2G Ex ib IIC T4 Gb), supporting explosive gas/dust environments. With 138 microphones and intrinsic safety, it delivers reliable PD, gas leak, and mechanical fault detection.

Partial discharge (PD) occurs when localized electrical breakdowns partially bridge insulation gaps without creating a full short circuit. These micro-discharges generate high-frequency electromagnetic waves, ultrasonic emissions (20-500 kHz), and chemical byproducts like ozone. Left unchecked, PD accelerates insulation degradation, leading to catastrophic equipment failures.
Corona Discharge: Sharp conductor ionization → Hissing sounds, ozone odor.
Surface Discharge: Insulation tracking → Crackling noise, carbonized patterns.
Internal Voids: Gas breakdown in solids → Repetitive “ticking” ultrasound.
Floating Electrodes: Loose metal sparks → Intermittent sparks, localized heat.
Our acoustic cameras leverage ultrasonic phased-array technology and AI analytics to:
Precisely Locate PD Sources (±15cm accuracy) via real-time sound visualization at 200m.
Classify PD Types with high accurate and Assess Severity using PRPD mapping.

HERTZINNO offers a free PC-based analysis software that allows users to import images and videos from their devices for secondary analysis. The software also supports video and image review, as well as report export.
Ultrasonic detection of compressed gas leaks operates by capturing high-frequency sound waves (20-100 kHz) generated by turbulent gas flow through leaks, where smaller orifices produce higher frequencies, enabling precise localization and quantification.
Acoustic cameras detect pressure-driven leaks independent of gas composition, enabling universal application for compressed air, inert gases, hydrogen, SF₆, and all other pressurized gas leak detection.
For different types of leaks, HERTZINNO’s acoustic camera can detect compressed air, natural gas, hydrogen, oxygen, as well as other inert and toxic gas leaks from long distances.
At the same time, the HERTZINNO camera features a built-in leak analysis function, allowing it to estimate leakage volume while locating the source, helping users more effectively assess potential losses.
Mechanical Abnormal Sound Detection
Characteristic noise is generated by bearing damage, blade imbalance, misalignment and other faults in rotating equipment.(e.g. motors, gearboxes, fans).
Hertzinno acoustic camera can capture the sound field distribution through the microphone array and generates a real-time heat map of the sound source. Pinpointing the location of the abnormal sound source and shortening the troubleshooting times.
