Manufactured by SubSurface Leak Detection, Inc.


The LC-2500 correlator is used to automatically pinpoint the precise location of the most difficult to find water leaks in pipes.

Compact and Light-Weight

The Main Processor Unit, weighing less than 7 lb., can easily be carried all day.


Ruggedly Built and Weather-Tight

The Main Processor Unit and the Pre-Amps/Transmitters can operate in rain storms, sub-zero temps., and direct sun for hours.

No Built-In Rechargables

Runs all day on standard or rechargeable D batteries.

Easy to Set Up and Run

Input pipe materials, diameters, and lengths by simply selecting them in the program menus. The automatic functions can do the rest.


High Sensitivity Sensors Standard

The new LC-2500 sensors are very sensitive, small in diameter, and totally submersible.
