Techno-AC - Model AT-407N -Water Leak Detector

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
