SubSurface Leak Detection LD-18 Digital Water Leak Detector

SubSurface LD-18 Digital Water Leak Detector

Designed to detect, survey, and pinpoint water leaks with precision and reliability.

The LD-18 is a fully digital leak detector built for use in noisy environments. It amplifies leak sounds while filtering out intermittent interference, allowing operators to focus on true leak signals without distraction. By capturing and logging sound levels at multiple locations, it provides both immediate results in the field and a record for later analysis.

Advanced Digital Amplification with Noise Suppression

The LD-18 incorporates automatic real-time noise suppression that blocks intermittent interference from sources such as passing vehicles, foot traffic, or conversation. With a combined sensitivity and amplification of 900 V/G at 400 Hz, it delivers clear leak sound detection across a wide frequency spectrum.

Flexible Detection Filter Options

Operators can choose between five high-frequency filters and three low-frequency filters to adapt the instrument to various pipe materials and conditions. Two notch filters are also available to eliminate steady sources of interference such as AC hum, motors, or wind noise. This range of options gives the LD-18 the versatility to function effectively in diverse environments.

Robust Hardware and Sensor Design

The amplifier housing measures 6.4 by 3.0 by 5.7 inches and weighs approximately 35 ounces with batteries installed. It carries an IP52 rating for dust and water resistance, while the ceramic piezoelectric sensor is IP67 rated and capable of being submerged to a depth of three feet for up to 30 minutes.

Durable and Field-Ready

The LD-18 is designed to perform in demanding conditions, operating in temperatures from -4 °F to 130 °F. It comes with a ground microphone and hand switch, base plate, aviation-style stereo headphones, padded amplifier case, USB cable, waist strap, and screwdriver, all stored in a rugged ABS carrying case.

Why Field Operators Choose the LD-18

The LD-18 combines digital noise suppression, flexible filtering, visual and audio feedback, and rugged construction in one portable system. It is trusted by utilities, municipalities, and maintenance professionals who need reliable leak detection under challenging conditions.
