Hand-held industrial acoustic imager is widely used in power station discharge, gas leakage detection under pressure or vacuum conditions, air tightness detection, equipment abnormal sound positioning and other scenarios. The instrument uses the microphone array beamforming technology to obtain the sound source distribution data, and the HD camera collects the video picture in real time. By integrating the sound source distribution data with the video image, the changing sound source dynamic is presented on the display screen. It can help the on-site inspection personnel to quickly locate the faults and provide the disposal basis.
