DatasheetThe HIKMICRO AI76 acoustic imaging camera is a professional product for gas leak detection and partial
discharge detection. With 136 Low-noise MEMS microphones and an adjustable bandwidth range from 0 kHz to 96
kHz, AI76 provides an easy and effective way to locate pressurized air leaks in industrial environments or detect
partial discharge in electric systems. By using a large 4.3″ LCD touch screen, the results presented on top of a
digital picture allow you to quickly find the source of the problems. Analyzer Acoustic software can analyze images
captured by acoustic imaging cameras and export reports. By adopting this lightweight and easy-to-use tool, you
can discover potential safety risks, minimize troubleshooting, and save extra costs for equipment failures and
downtime.
