AT-407N

AT-407N – Water leak detector

AT-407NAT-407N – Basic acoustic water leak detector for metal and non-metal underground pipelines under paved and unpaved surfaces.

Features AT-407N

  • 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 AT-407N

  • 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 AT-407N

  • 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
