Function and Design
The Hydrolux HL 50 by SebaKMT is an easy-to-use and handy device for acoustic leak
detection on water pipes.
The HL 50 comes with an integrated acoustic sensor. The pipe noise is recorded via the
probe tip, internally amplified, filtered (if needed) and played via wireless headphones.
At the same time, the measured noise level is shown on the display of the device.
During the measurement, the user can select from three frequency filter settings.
The probe tip can be removed. This way, prolongation sticks or other probes can be
installed.
Using the sensor socket, an external acoustic sensor can be connected to the HL 50,
e.g. a ground microphone.
Instead of wireless headphones, also corded headphones can be used.
The following picture shows the probe tip, sensor and the connection sockets of the
device.
