SubSurface Instruments Analog Function, Digital Display Water Leak Detector

Model Number: LD-20

The SubSurface Instruments LD-20 Water Leak Detector combines traditional analog signal response with a clear digital display, providing water utility professionals, contractors, and maintenance crews with an effective solution for pinpointing underground water leaks. Designed for ease of use and dependable field performance, the LD-20 helps locate leaks in water distribution systems, service lines, hydrants, and valves by amplifying leak-generated sounds that travel through pipes and surrounding soil.

Its dual analog and digital display system allows operators to both hear and visualize leak intensity, making it easier to identify the leak point with greater accuracy. The lightweight, portable design is ideal for routine system inspections, leak surveys, and preventative maintenance programs.
