HIKMICRO AI56L Acoustic Imaging Camera – 64-Microphone Gas Leak Detection

AI56L

The HIKMICRO AI56L Acoustic Imaging Camera is a professional handheld acoustic camera designed for fast and effective compressed air and gas leak detection in industrial environments.

Using 64 low-noise MEMS microphones and real-time sound source localisation, the AI56L helps technicians quickly identify the source of pressurised air leaks, gas leaks, and ultrasonic sound emissions without direct contact.

With an adjustable acoustic bandwidth from 0 kHz to 96 kHz, an acoustic image resolution of 800 × 480, a 4.3" LCD touchscreen, and a detection distance from 0.3 m to 150 m, the AI56L provides a practical and efficient way to reduce energy waste, improve maintenance efficiency, and support preventative maintenance programs.

The AI56L also provides real-time estimated leak rate, leak cost, and leak level information, helping maintenance teams prioritise repairs and better understand the financial impact of compressed air and gas leaks across a site.

Designed for industrial field use, the AI56L features a rugged IP54 rated body, interchangeable rechargeable battery system, Wi-Fi, USB Type-C, HDMI connectivity, image and video storage, and support for HIKMICRO acoustic analysis software for reviewing images and exporting reports.

Professional Acoustic Imaging for Compressed Air and Gas Leak Detection

The HIKMICRO AI56L Acoustic Imaging Camera gives maintenance teams a fast and practical way to locate compressed air and gas leaks using real-time acoustic imaging.

By visualising ultrasonic sound sources on the camera display, the AI56L helps users quickly identify leak locations without needing direct contact with pipework, fittings, pneumatic equipment, or machinery. This can help reduce inspection time, minimise energy waste, and support more efficient maintenance planning.

With real-time leak rate, leak cost, and leak level estimation, the AI56L provides more than simple leak location. It helps technicians understand the potential impact of leaks, prioritise repair work, and document findings using images, videos, annotations, and HIKMICRO acoustic analysis software.
