Fluke ii905 Acoustic Imager with LeakQ™: Detect, Locate, and Assess Gas Leaks

The Fluke ii905 Acoustic Imager equipped with LeakQ™ acoustic leak detection technology empowers maintenance teams to efficiently detect, locate, and assess gas and vacuum leaks. Whether you're dealing with compressed air systems, pipelines, or industrial equipment, the Fluke ii905 provides valuable insights to optimize your operations.

Key Features:

  • Ready-to-Use: The Fluke ii905 comes ready out of the box. Its rugged, ergonomic design ensures easy handling, while the large 7" LCD display provides clear leak visualization.
  • Quick Detection: Even users with minimal experience can start detecting leaks within minutes. The tool estimates leak size and cost, incorporating a new distance-estimation feature and the 1-10 LeakQ™ severity index.
  • SoundMap™ Overlay: The 7" LCD touchscreen overlays a SoundMap™ on visual images, facilitating rapid leak location identification.
  • Intuitive Interface: Easily isolate leak sound frequencies and filter out background noise.
  • Tagging and Organization: Use image and video tagging, annotation, and folders for efficient organization.
  • Leak Sizing: Prioritize repairs based on leak size.
  • Collaboration: The reporting tool allows seamless sharing of visuals, tagging, and notes with team members and repair personnel.

Money-Saving Insights:

Did you know that a 100 hp air compressor can consume around $50,000 in electricity annually? Shockingly, up to 30% of that electricity is wasted due to pressurizing airlines that leak. Many facilities overlook assessing the efficiency of their compressed air systems, leading to unnecessary capacity additions. The Fluke ii905 helps you identify leaks, optimize energy usage, and reduce costs.

LeakQ™ Mode:

Automatic Distance Estimation: When a leak is detected, the imager determines the distance to the target (indicated inside the circle on the display). The LeakQ value on the screen reflects the leak's size, based on measured dB SPL value and distance.

Comprehensive Reporting:

The LeakQ reporting tool combines data from your Fluke ii905 Acoustic Imager with direct inputs to create organized and detailed reports. These reports guide repairs, confirm fixes post-repair, and document the inspection process and results.

LeakQ online reporting tool

  • Local PC installed application
  • No Leak Type selection (should be included at the time of capturing the measurement)
  • Offers customization of reporting template
