Description
The new LD-18 Digital Water Leak Detector is the first water leak detecting instrument to offer automatic noise reduction from intermittent interfering noises, like passing vehicles, people talking, and pedestrian footsteps.
This leak detector finds leaks quickly and easily. Amplifier easily identifies leak sounds.
All-digital amplifier with automatic noise reduction of environmental sounds, high and low filters, storage and graphing of leak noises at different locations on pipe.
Uses bar graph and numeric display of sound loudness, USB connection, and back light.
Five High Frequency filters, Three Low Frequency filters(plus Low filter OFF), and 2 Notch filters(plus Notch filter OFF) to remove continuous interfering noises.


LD-18 Amplifier showing filter settings, bar graph and numeric display of sound loudness, and minimum sound level detected.
Automatic noise reduction capability for intermittent noises such as pedestrian footsteps, people talking, and passing vehicles.
5 High Frequency filters, 3 Low Frequency filters (plus Low filter OFF), and 2 Notch filters (plus Notch filter OFF) to remove continuous interfering noises from A/C hum, motors, wind, etc.
The “Saved” data file shows 10 leak sound levels and a graphical display. The leak is at the peak sound level in the center.
With the Minimum Noise Levels saved at 5 – 10 spots directly over the pipe, examine the GRAPH by pressing FILE twice.
The Minimum Noise Level at each spot is the actual leak sound, and where it reaches a peak is where the leak is pinpointed.
