How fast will you find your first leak?

Right out of the box, the Fluke ii900 is ready to use. It’s rugged and ergonomic design make it easy to handle and the large 7” LCD display make leaks easy to see. Within minutes, a user with little-to-no experience can start detecting leaks. When the Fluke engineers were considering the users of the ii900, they wanted to make sure all the necessary components were built-in and easy to access. In addition, the Fluke engineers knew shutting down the plant or putting technicians in harm’s way was out of the question—that’s why they made sure the Fluke ii900 Industrial Acoustic Imager could be used in noisy environments and from a safe distance.

You can actually see money leaking right out of your system

A 100 hp air compressor can consume around $50k in electricity annually and as much as 30% of that electricity goes toward pressurizing airlines that leak. Many facilities have never assessed the efficiency of their compressed air operation and thus, when the system appears to be slowing down or not keeping up with demand, the facilities simply add more capacity. An expensive purchase considering compressed air systems should have relatively little change in capacity over time unless demand has increased, or the system is being sabotaged by leaks.

More than you expected, by far

  • 7” LCD touchscreen that overlays a SoundMap™ on a visual image for quick leak location identification
  • Straightforward, intuitive interface to isolate the sound frequency of the leak and filter out loud background noise
  • Image and video tagging, annotation, and organization using folders
  • Leak sizing to help determine priority for repairs
  • Report tool to share visuals, tagging, notes, and more with others on your team or repair personnel

Communication and reporting tools for everyone

The Fluke ii900 comes enabled with LeakQ mode, which automatically determines the distance to the target (a leak that shows inside the circle on the display). When a leak is detected and the imager can determine the distance, the LeakQ value on the display gives in indication of the size of the leak. The value is based on the measured dB SPL value and the distance.

The LeakQ reporting tool combines the inputs from your Fluke ii900 Industrial Acoustic Imager with inputs made directly to the tool to create organized and detailed reports. These reports can be used to convey where repairs need to be made, for follow-up post repair to confirm fixes, or for simply documenting the inspection process and results.

How do you see sound?

The Fluke ii900 Industrial Acoustic Imager visualizes the sounds coming from small leaks in compressed air, gas, and vacuum systems. Equipped with an array of microphones for an expanded field-of-view, the handheld Fluke ii900 Industrial Acoustic Imager (Sonic Industrial Imager) enables maintenance teams to locate air, gas, and vacuum leaks quickly and accurately in compressed air systems—even in noisy environments. Specifically designed for noisy production facilities the new SoundSight™ technology is simple to learn and easy to implement.

Given that the fluke ii900 is measure's accustic (Sound level) will it work in a noisy environment? While production lines are running next to it?

Asked by: ACONTR
Yes, the Fluke ii900 Industrial Acoustic Imager will work in noisy environments, but depending on noise level can play a factor in what is being read.

Can this find Natural Gas leaks?

Asked by: Doug Power Plant Tech
The Fluke ii900 Industrial Acoustic Imager measures sound, which means if the leak has enough volume/sound the Fluke ii900 Industrial Acoustic Imager can pick it up. We also have a resource that may provide additional information: https://dam-assets.fluke.com/s3fs-public/6013561a-en-ii900-case-study-localize-leaks-ngsi-w.pdf?Py6cafJVLlmeUAUFTNsOXOY2heECqKlp

What is the reading capability like for Steam Leaks? Are there any resources about Steam Leak Detection?

Asked by: Brian MRO
The Fluke ii900 Industrial Acoustic Imager can identify and locate steam, but not quantify the amount.

Rated 5 out of 5 by from Incredible Tool This is an incredible tool for finding leaks. We used the ii910. It has also been used for finding partial electrical discharges on insulators.

Rated 5 out of 5 by from Time Saver! I have used the ii900 for 8 months now and it is absolutely amazing. This will find air leaks you cannot hear including in a loud environment. Storing photos of the leak and the information from the leak all on the tool. I upload the files to the computer and use flukes software to create a report and it even estimates the cost of the leak.
