3 Application

The S531 is a hand-held ultrasonic leak detector that helps you quickly

detect and provides quantitative data for the leakages in compressed air

or any pressurized gas systems.

Gas leaks emit ultrasound, however the frequency is too high to hear by

human ear directly. The S531 converts the leak ultrasound to a lower

frequency that can be heard through headphones from several meters

away, which leads you to find the leak source.

In unpressurised systems, you can use an ultrasonic tone generator to

generate sounds that can be detected by the S531.

To efficiently manage the leak data, SUTO offers the Leak Management

Software (LMS) for your need. The LMS provides a total solution for leak

detection, management and easy report creation.

This manual takes you through how to use the S531.

4 Features

•Detects leaks in the compressed air or gas system easily even

from distance.

•Supports high resolution 3.5” color touch screen, easing

operations in leak detection.

•Supports wireless connection with headset.

•Builds in camera to take photo of leak locations.

•Provides voice recorder for voice memos.

•Equips with laser pointer to pinpoint leak locations.

•Records leak information for statistics and repair.

•Calculates air loss in l/min, m3/h or cfm and in the local currency

•Integrates noise reduction technology.

•Supports battery capacity for up to 6 hours.
