The S531 ultrasonic leak detector is an advanced solution for fast and efficient detection of leaks in compressed air, gas, and pneumatic systems, even from a distance. The built‑in touch screen, laser pointer, and intuitive interface ensure ease of use even in demanding industrial environments.
Compressed air leaks force compressors to run under increased load, leading to higher electricity costs. Timely detection and repair of leaks using the S531 can reduce energy consumption by up to 30 % – providing a rapid return on investment.
The instrument helps users quickly locate and record leaks: point the laser pointer at the suspected area – the leak level is displayed on the screen. For precise pinpointing, use scanning at medium distance or the focus tube with focus tip. The built‑in camera and microphone allow taking photos and recording voice memos for each detected leak – simplifying subsequent tracking and repair.
Thanks to the combination of portability, touch‑screen operation, photo documentation, and voice memos, the S531 makes leak surveys more flexible and reporting highly informative. It is the ideal solution for energy audits, routine inspections, and rapid response to losses in pneumatic systems.
Integration with Leak Management Software (LMS)
The S531 is designed to work with the SUTO Leak Management Software (LMS), which enables companies to systematically manage their leak detection and repair processes. An LMS license is included free of charge with the instrument – allowing you to immediately start generating detailed leak reports without additional software costs.
