Imager Pinpoints Leaks in Minutes


According to the Compressed Air and Gas Institute (CAGI), the average compressed air system loses 30% of its air through leaks but locating those leaks has been a time-consuming and tedious process. The Fluke ii900 Sonic Industrial Imager enables maintenance teams to quickly and visually pinpoint the location of compressed air, gas, and vacuum system leaks even during peak production periods - all in a matter of minutes.


With minimal training, technicians can identify compressed air leaks considerably faster than using traditional diagnostic methods. Now checking for air leaks can be performed during the typical maintenance routine.


An array of microphones combined with SoundSight technology, the handheld Fluke ii900 Sonic Industrial Imager filters out background noise so maintenance teams can accurately locate leaks in compressed air systems, even in the noisiest environments.


Inspect an entire plant in hours

The seven-inch LCD touchscreen overlays a SoundMap on a visual image for quick leak location identification. The straightforward, intuitive interface allows technicians to isolate the sound frequency of the leak to filter out loud background noise. In a matter of hours, the team can inspect the entire plant – during peak operations. Images can be saved and exported for reporting purposes.


Acoustic imaging combined with industrial diagnostics

The Fluke ii900 was designed in partnership with Sorama, an Eindhoven-based company specializing in noise control and sound analysis solutions. The combination of Sorama’s long history and expertise in acoustic imaging and Fluke’s leadership in diagnostic industrial test and measurement equipment lead to the creation of a tool that has the durability and usability required for industrial maintenance applications.
