HVHIPOT GDUI-411PD 0.3~150m High Accuracy Handheld 64 Microphone Acoustic PD Camera Gas Leakage Tester

Product Description

Product Description

The GDUI-411PD is a handheld industrial acoustic imager widely used in various scenarios such as power partial discharge detection, gas leak detection under pressurized or vacuum conditions, airtightness testing, and equipment noise localization. The instrument utilizes microphone array beamforming technology to acquire sound source distribution data and, in conjunction with a high-definition camera, captures video footage in real time. By fusing the sound source distribution data with the video images, the changing sound sources are dynamically presented on the display screen. This helps on-site inspection personnel quickly locate faults and provides a basis for handling them.
