Powerful and intelligent– hear the inaudible
noise

Simple operationand versatile forall situations

Built for frequent
use and a long life

With ground microphone or electronic
listening stick

The unique feature “FrequencyShifting” makes audible what
was once not audible: It lifts
otherwise inaudible low
frequency noise (below 30 Hz)
that is common for leaks inplastic pipes or large diameter
pipes to a higher, readily
audible frequency band.

With only 2 buttons/dials on
the control unit and 3 pre-set
filter ranges, the operation of
the AQUASCOPE 550 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 asecond operator to listen in.

The AQUASCOPE 550 has anergonomic design and a very
solid, yet light-weight bodythat was designed specificallyfor utilities that are faced withthe everyday challenge offinding leaks on plastic andlarge diameter pipes. The
microphones are constructedof robust high-grade stainlesssteel and rubber for comfortand stability.

The “Minimum Level Profiling”
function enables the operator
to record leak values that are
independent of passing trafficand other ambient noises. TheAQUASCOPE 550 latches tothe lowest noise recorded ateach sounding. The last eightreadings are displayed as bar
chart showing the operator
whether he is moving awayfrom or closer to the leak.

The AQUASCOPE 550 ishighly reliable and virtuallymaintenance-free whichmakes it an extremely
cost-effective productover its expected lifetime.
GUTERMANN provides a2-year factory warranty likeon all other products fromGUTERMANN.

The AQUASCOPE 550 comeswith the choice of either aground microphone or anelectronic listening stick(hand probe), or as combined
kit. The ground microphone‘foot’ is robust, weather proof
and acoustically shieldedagainst non-leak interference.
It is particularly suitable forleak surveys on flat grounds
and roads. The versatile
hand probe incorporates ahandle and the same highperformance sensor as theground microphone. It andallows direct listening onfittings or – with a tripod footmagnetically attached to it –on soft grounds and on walls.

Manual filters are userprogrammable in blocksof 40Hz. A large graphicaldisplay transforms the
crystal digital sound into avisual frequency spectrum
showing a clear peak of theleak and aiding the advanced
technician to pinpoint themost difficult leaks with ease.
