Visually Pinpoint Leaks in Non-Pressurized Spaces

Traditional leak detection in sealed spaces is slow, unreliable, and labor-intensive. The Fluke SB140 Sound Beacon, paired with a Fluke Acoustic Imager, brings speed, precision, and simplicity to leak detection and tightness testing. Whether you're inspecting sealed EV battery compartments, aircraft cabins, or cleanroom doors, this ultrasonic solution reveals leak paths without the need for pressurization. Instead of relying on slow, error-prone, and labor-intensive methods, technicians can now visualize leak locations directly on screen—making the process not only faster, but also more reliable and repeatable.
Smarter Leak Detection with the Fluke SB140 Kit
The Fluke SB140 Sound Beacon offers a safe, precise alternative to traditional leak detection, especially in environments where pressurizing isn't possible. It emits a 40 kHz ultrasound signal that Fluke Acoustic Imagers detect and visualize, helping teams pinpoint leaks quickly and confidently.
