Description

The LD-15 Professional’s Leak Survey Instrument is primarily designed for water leak “surveys”. Use this to quickly identify problem areas (by listening at hydrants, valves, and meters) and/or isolate a leak between points of contact along the pipe.

Features

• High sensitivity sensor with Neodymium magnet (extra strong). Sensor and cable connection completely sealed and water-proof (submersible).
• Amplifier with superior audio quality (very low distortion and superior signal-to-noise ratio) and large meter display. Press the Mute Switch to hear sounds when you are ready.
• “Survey” for water leaks by listening at hydrants and valves with the sensor and magnet. Survey at water meters with the optional Long Contact Rod.
• “Pinpoint” water leaks in pipes under asphalt or concrete with the base plate attached to the sensor and magnet.
• Use the High filter range for water leak surveying. Use the Low filter range for water leak pinpointing. High frequency leak sounds travel on the pipes, but only low frequencies pass through the soil.
