Product Description

The MPB568 Acoustic Imager is a smart detection device designed for partial discharge monitoring and gas leak detection in high-voltage systems. Equipped with 138 low-noise MEMS microphones, it captures an extended acoustic spectrum from 2kHz to 100kHz, enabling precise sound source localization even from long distances.

The MPB568 can intelligently identify corona, floating, and surface discharges, making hidden flaws visible and easy to trace. With a detection range of 0.3 to 150 meters, a 13MP digital camera, and advanced acoustic imaging modes (single, multi, hologram), it delivers unmatched reliability for predictive maintenance and inspection.
