The Fluke ii900/ii910 is an Acoustic Imager (the Product or Imager) that detects and locates an acoustic signature. These signatures can indicate leaks in compressed air, compressed gas, and vacuum systems.

In addition, the ii910 detects electrical discharges as well as leaks. These electrical discharges include partial discharges such as corona, surface tracking, and arcing.

The ii910 also identifies and locates potential mechanical issues. The Imager has an acoustic sensor array that aligns a sound source heatmap with the image. The visible-light camera provides a live-view image of the inspection area. Capture and save still image files and video files from the inspection for documentation and reports.

A rechargeable battery powers the Imager. The Imager includes an external battery charger with a power adapter and country-specific cables.

The Imager has a USB-C port that connects to a PC for file download and firmware updates.
