Water Leak Detector "AT-407N"

Basic acoustic water leak detector for metal and non-metal underground pipelines under paved and unpaved surfaces.

 

Features :

·      AP-027 digital location receiver

·      Acoustic sensor AD- 227

·      Visual and audio indication of the signal

·      Omission of parasitic noise

·      Precise sensitivity adjustment

 

Brief Description :

·      Storage of 31 signal level with a graph displayed

·      Acoustic sensor spectrum with ability to choose frequency minimum background noise

·      Graphic visualization (moving chart) of sequence of measurements, max and min signal levels

·      Sound indication

·      Protection from random acoustic noise

·      Choice of bandwidth

·      Two-segment indication of frequency spectrum (and “filtered”) signal

·      Light weight

 

Application :

·      Water leak detection from the pipelines (plastic or metal) underground up to 6 m depth

·      Water leak detection inside the house

 

Sensitive acoustic sensor AD allows to find the leak :

·      Under paved and unpaved surfaces

·      By direct contact on the pipeline

·      By placing the sensor against the wall

·      LCD display

·      Memory of 31 signal level

·      Graphic visualization of the signal

·      Protection from random acoustic noise

·      Light weight

·      Comfortable to wear for long terms
