The HIKMICRO AI76 is an acoustic imaging camera designed for the detection of gas leaks and partial discharges. It is equipped with 136 low-noise MEMS microphones and offers a flexible bandwidth range from 0 kHz to 96 kHz. The instrument features a large 4.3" LCD touch screen, which displays results superimposed on a digital image, enabling users to swiftly pinpoint problem sources.
The accompanying Analyser Acoustic software can process images taken by the AI76 and generate reports. Utilising this compact and user-friendly instrument can help uncover potential safety hazards, streamline troubleshooting processes, and prevent additional expenses associated with equipment malfunctions and operational interruptions.
