Megger MPAC128 Acoustic Imager
Megger MPAC128 Acoustic Imager helps users locate gas leaks and partial discharge faults from a safe distance. It can detect issues from up to 120 metres away while giving clear visual guidance. As a result, engineers can respond faster and reduce downtime in busy work areas.
Built with 128 MEMS microphones, this acoustic imager captures ultrasonic signals with high precision. It also uses intelligent analysis tools to help identify different discharge types. In addition, the simple interface keeps operation easy with only two main settings to adjust.
Advanced acoustic detection
The Megger MPAC128 Acoustic Imager converts ultrasonic sounds into audible signals for accurate leak pinpointing. A focus function also helps reduce unwanted background noise in loud environments. This allows users to work more effectively in factories, process plants and electrical sites.
PRPD analysis helps users separate different forms of partial discharge during inspection work. Leak rate quantification also supports cost estimation and repair planning. Therefore, teams can make informed maintenance decisions using clear and reliable data.
Designed for demanding environments
A 7 inch capacitive touch screen gives clear viewing during field work. The 8 megapixel camera captures detailed images while the 1024 x 600 display keeps information easy to read. Megger MPAC128 Acoustic Imager also offers IP54 protection for use in harsh working conditions.
Internal 8 GB storage allows users to save images, video and audio files directly on the device. A rechargeable 6600 mAh Li-ion battery provides up to four hours of operation under full load. Overall, the Megger MPAC128 Acoustic Imager combines strong acoustic performance with practical site-ready features.
