Lecksucher LS 01



Pressurised water creates noises when escaping which propagate across the water column, pipe and soil. These noises can be recorded, amplified and made audible to the human ear with the LS 01.

The LS-01 has been developed by experienced specialists as a listening device to prelocate and pinpoint leakages in water networks and indoor water installations. The device is characterized by its low weight and easy operation. The microphone technology allows to record noises over a very large spectrum. The LS-01 is suitable for all pipe materials as the frequency response of the microphone is between 35 Hz and 2000 Hz. The LS-01 is suitable for all applications of leak detection and noise detection as a monitoring device for fast use with a short tip or brought to test rod length by two extensions. A resonance plate and a magnet in the accessories program make it possible to detect underground noises or leakage noises in the installation area or on solid surfaces. The LS 01 is operated via a volume control and a button for activating the amplifier. The signals are transmitted to the user's ear via headphones.
