Features

  • Easy, fast, and safe visual detection of compressed gas leaks with LeakQ™ mode, including estimated leak size and cost.
  • The 7-inch LCD touchscreen overlays a SoundMap™ on visual images, enabling rapid identification of leak locations.
  • Integrated visual and text tagging and annotation functions provide essential information to streamline reporting and follow-up actions.
  • Wireless upload to Fluke Connect while on the go.

 
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.

Local PC installed application
No Leak Type selection (should be included at the time of capturing the measurement)
