1. Introduction
Cygnus DIVE Underwater Thickness Gauge
The Cygnus DIVE Underwater Thickness Gauge has been
specifically designed for the professional diver undertaking metal
thickness surveys in both shallow and deep water sites. It has
been design to withstand the extreme environments encountered
while providing quick, clear and accurate metal thickness
measurements using the Cygnus Multiple Echo technique and
Single Echo / Echo-Echo options.
The Cygnus DIVE Underwater Thickness gauge is pressure rated to
a maximum depth of 300 meters sea water (984 ft).
The gauge can be worn on the diver’s fore-arm allowing one hand
to remain free while carrying out the thickness survey. A bright
colour AMOLED display shows the thickness measurement in large
numbers. Thickness measurements are further backed up by an A-
scan display. Measurement data can be sent to the surface via a
RS-485 serial data link where they can be data logged and used to
produce a survey report using Cygnus’ CygLink software.
Measurements can be displayed in Metric (mm) or Imperial (inch)
units and measurement resolution can be selected from 0.011,
0.05 or 0.1 mm, (0.0012, 0.002 or 0.005 inch). Thickness
measurements can easily be calibrated to a known thickness or to
a known Velocity of Sound.
The gauge is a solid-state electronic instrument which, under
normal operating conditions, will give many years of active
service.
Although designed for ease of operation first time users
should carefully read this manual to familiarise themselves
with the features of the gauge

Cygnus Instruments
Cygnus Instruments Limited, founded in 1983, pioneered the
development of the Digital Ultrasonic Multiple-Echo Technique
used for measurement through coatings. This has long since been
the standard required to ensure that accurate measurements are
taken without the need to zero the gauge or remove any coatings
first.
Our philosophy is to work closely our customers to provide high
quality products, engineered to serve heavy industry & harsh
environments. Cygnus Ultrasonic thickness gauges are designed to
be reliable and simple to use. We have an unrivalled reputation in
over 45 countries around the world.
