SGM - SERIES WATER LEAK DETECTORS

Water leak detection with the Professional SGM Series is a non-destructive and efficient method for locating leaks in underground pipes and infrastructure. It helps minimise water wastage prevents costly water damage, and avoid excavation and disruption to the surrounding area by precisely pinpointing the leak's location. This technique is commonly used by professional plumbing and utility companies as well as municipal water departments to maintain water systems and minιmise water loss.

The SGM Series acoustic leak detection devices are sensitive instruments designed for water leak detection by capturing and amplifying the sounds generated by water escaping from buried pressurised pipes, and used to identify and locate underground water leaks in water mains, as well as other water infrastructure.

The SGM Series is the latest generation of high accuracy underground water leak detectors. The SGM Series features touch screen operation and a wealth of new innovative features.
The SGM Series is suitable for underground metallic and non-metallic pressure piping and can work on hard and soft surfaces in different depths i.e.
SGM200 5000Hz 2m   SGM300 6000Hz 3m   SGM400 7000Hz 4m    SGM500 8000Hz 5m   SGM600 9000Hz 6m

KEY BENEFITS
Combines the dual-mode function acoustic vibration with spectrum technology to determine the accurate leakage
Equipped with the windproof sensor and super anti-jamming filtering environmental noise
Setting active noise reduction function to exclude external interference and locate the leakage position
Applicable to all kinds of pipeline material and ground surfaces

WATER LEAK DETECTORS FOR INDOOR SPACES

Sigma SGL-Series Indoor Water Leak Detectors

Professional Acoustic Leak Detection for Buildings and Indoor Water Pipe Networks

The Sigma SGL-Series represents the latest generation of intelligent acoustic water leak detectors, engineered for the fast and accurate location of hidden leaks in pressurised water pipes within residential, commercial, and industrial buildings.

By capturing, amplifying, and analysing the unique acoustic signals generated by escaping water, the SGL-Series enables maintenance professionals and plumbers to pinpoint concealed leaks quickly and non-destructively—reducing unnecessary wall or floor demolition, minimising repair costs, and shortening inspection time.

Designed specifically for indoor applications, the instrument includes two high-sensitivity sensors:

Triangular Sensor – optimised for horizontal surfaces such as floors.
Square Sensor – designed for vertical surfaces including walls, columns, and cabinets.

Combined with an intuitive 7-inch HD touchscreen and real-time spectrum analysis, the SGL-Series allows users to identify even subtle leak sounds with exceptional precision.
