Product description
Electroacoustic leak detection using ground microphones, probe rods, and tracer gas
The HL 7000 ground microphone system for electroacoustic leak detection is a modern device for locating leaks in drinking water networks (with a search rod and tracer gas), which offers a wide range of applications thanks to its flexible design and automatic 360° sensor detection. This adaptability allows leaks to be located precisely and efficiently in a wide variety of situations. Thanks to its powerful lithium-ion batteries, the system can be used for over 10 hours without interruption, making it perfect for extended use.
The Smart Solution for Everyday Use
With the HL7000 Light, SebaKMT® offers a compact and efficient set specifically designed for mobile use in daily operations. It is aimed at users who do not want to miss out on the full performance of the HL7000 system but consciously choose to forego additional accessories.
Ideal for smaller network areas, house connections, or targeted damage analyses. The control unit is identical to that of the Pro Set, including touchscreen, frequency analysis, and GPS, combined with the proven wired ground microphone PAM W-7-C and a telescopic rod. The components are not housed in a transport case but in a robust, lightweight carrying bag, perfect for quick access on the go. The HL7000 Light is a reliable and efficient companion for utilities, municipalities, and service providers looking for a compact solution with professional precision.
A key feature of the HL 7000 Light is the Bluetooth®-enabled, wind-protected piezo ground microphone with built-in preamplification. This microphone is specially designed to reproduce very low leak frequencies on soft materials such as PVC or PE just as clearly as high frequencies on hard materials such as steel or cast iron pipes. This versatility and the ability to accurately detect various frequency ranges ensure reliable leak detection under a wide range of conditions.
The HL 7000 Light ground microphone system is a powerful and robust tool that greatly increases the efficiency and accuracy of your leak detection thanks to its advanced technology and sophisticated design.
