The AquaScope 550 Acoustic Leak Detection kit from Gutermann is designed specifically for the professional leak hunter who often has to find the difficult leaks that nobody else can find. Leaks in PVC water mains, trunk mains and low pressure water networks can be an extremlely low frequency not audible to the human ear even if the noise is amplified. The Aquascope 550 acoustic leak detection kit has a special frequency shifting mode to enable the operator to find and pinpoint those leaks that have been considered impossible to find with acoustic technology in the past. Gutermann is world renowned for producing the most innovative and effective acoustic leak detection kit technology.

Features and benefits

Powerful and intelligent – hear the inaudible noise: The unique feature “Frequency Shifting” makes audible what was once not audible. It lifts otherwise inaudible low frequency noise (below 30 Hz) that is common for leaks in plastic pipes or large diameter pipes to a higher, readily audible frequency band.

Flexible manual filters are user programmable in blocks of 40Hz. A large graphical display transforms the crystal digital sound into a visual frequency spectrum showing a clear peak of the leak and aiding the advanced technician to pinpoint the most difficult leaks with ease.

Simple operation and versatile for all situations: With only 2 buttons/dials on the control unit and 3 pre-set filter ranges, the operation of the Aquascope 550 acoustic leak detection kit is very quick and easy. The amplifier can also be activated and deactivated with a trigger button directly on the microphone, leaving the other hand free to carry other tools. A twin headphone socket enables a second operator to listen in.

The “Minimum Level Profiling” function enables the operator to record leak values that are independent of passing traffic and other ambient noises. The Aquascope 550 acoustic leak detection kit latches to the lowest noise recorded at each sounding. The last eight readings are displayed as bar chart showing the operator whether he is moving away from or closer to the leak.

Built for frequent use and a long life: The AquaScope 550 Acoustic leak detection kit has an ergonomic design and a very solid, yet light-weight body that was designed specifically for utilities that are faced with the everyday challenge of finding leaks on plastic and large diameter pipes.
