LD-12 Water
Leak Detector

Easy-to-use water leak detector optimized for ground “miking” on streets & concrete slabs.

The LD-12 water leak detector is a very easy-to-use detector, featuring six filters that allow the unit to screen outside noise and zero in on water leaks. The LD-12 is a must for every water utility as it’s the professional’s water leak detector.

Standard includes amplifier with meter display and filter controls, ground microphone and hand switch, aviation-grade stereo headphones and heavy-duty ABS plastic carrying case.


Large meter display (with backlight) of sound loudness, allowing the user to pinpoint the exact leak location.

Light weight amplifier, weighing only 31 ounces, with a padded carrying case and a strap.

Six selectable filters, split into three “low side” filters (100Hz, 200Hz, or 400Hz) and three “high side” filters (600Hz, 800Hz, or 1200Hz).

“Limiter” switch which cuts off all loud noises greater than 110dB. If you drop the sensor, you won’t hurt your hearing.

“Filter-Thru” switch, which turns OFF all of the amp’s filters, allowing the user to hear all sounds from 50Hz to 15,000Hz.

High-sensitivity ground microphone and low “electronic noise” amplifier combine to offer the very best quality sound for leak detection.

Three accessories for attachment to the sensor: Ground plate for pinpointing on streets/slabs Magnet base for surveying at hydrants/valves Contact rod for surveying at meters/fittings
