Sound locator LD6

The ultra-compact solution for leak detection and pre-location in water supply

Using the LD6, you can quickly and safely check lines or fittings to detect sounds of leakage. The combination of a highly sensitive vibration sensor and appropriate amplifier technology allows to detect even minimal structure-borne sound waves.

At the push of a button, you can filter either high or low frequencies, which enables you to carry out successful measurements on both metallic and non-metallic lines. The wireless Bluetooth transmission to the headphones facilitates the measurement process considerably.

To carry out a measurement, you can place either the measuring tip of the LD6 or one of the accessories included in the scope of delivery on the line, fitting or floor. If there is a pipe burst in the line being inspected, a leak sound will be emitted at the respective spot.

The integrated level indicator additionally shows the intensity of the sound received.


How to find leaks using the LD6:

  1. Place the measuring tip of the LD6 on the test object.
  2. Watch the level on the LED indicator.
  3. A stable level indicates a leak or water withdrawal.
  4. If the sound level temporarily drops to zero, there is no leak.
  5. Switch on the wireless headphones and adjust the signal modulation for an ideal sound transmission.
  6. Measure at different points to track down the location of the leak.
