Description

Detect hidden leaks and electrical faults in seconds – even from a distance and in noisy environments.

The HertzInno HA3A is an acoustic camera designed for professional use that converts sound into a real-time image. It allows you to effortlessly locate compressed air leaks, gas leaks and partial discharges in the electrical network. This device is an essential tool for improving energy efficiency, saving on maintenance costs and ensuring workplace safety.

Why choose the HertzInno HA3A?

  • Highly accurate 128-microphone system: The device features 128 digital MEMS microphones, enabling exceptional sensitivity and accuracy. It can detect a gas leak as small as 0.0032 l/min from a distance of 2.5 metres.

  • Wide frequency range (2 kHz – 100 kHz): The HA3A covers both audible frequencies and the ultrasonic range, making it a versatile tool for analysing mechanical noise as well as detecting small leaks.

  • Visualise faults from a distance: Detect leaks and faults safely from 0.3 metres up to 150 metres away. A 13 MP optical camera and a bright 5-inch HD touchscreen ensure you can see the subject clearly in all conditions.

  • Smart and easy to use: Built-in artificial intelligence helps identify faults. You can add text, voice or photo annotations to images and videos directly in the field.

  • Lightweight and durable: Weighing less than 1.2 kg, the device is ergonomically designed for one-handed use. The IP54 protection rating ensures reliable operation in demanding industrial environments (-20°C to +55°C).

Applications:

  • Compressed air systems: Locate and repair leaks that cause unnecessary energy costs.

  • Gas leaks: Detect leaks of nitrogen, argon, helium and other industrial gases.

  • Electrical maintenance: Locate critical partial discharges (PD) in transformers and high-voltage power lines.

  • Mechanical condition monitoring: Identify abnormal mechanical noise before it leads to equipment failure.

Technical highlights:

  • Display: 5-inch capacitive touchscreen (1920×1080)

  • Storage: 128 GB internal memory (4K images and 1080p videos)

  • Battery: Li-ion battery with PD fast charging (charges from 10% to 90% in just 2.5 hours)

  • Connectivity: Wi-Fi, Bluetooth 4.2 and USB Type-C

  • Accessories: Integrated laser rangefinder (0.1–30 m) and electronic compass.

The HertzInno HA3A is an investment that quickly pays for itself through reduced energy wastage and avoided production downtime.
