Compact & Lightweight Leak Correlator.


Compact & Lightweight Leak Correlator.

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

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

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

Runs all day on standard or rechargeable “D” batteries.

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

The Main Processor Unit displays the correlation “picture” and the distances to the leak from the Red pre-amp transmitter and the Blue pre-amp transmitter.
