Cygnus Instruments is the leading manufacturer of reliable, rugged underwater thickness gauges for divers carrying out maintenance inspections and corrosion checks.

Developed with the Cygnus-pioneered Multiple Echo technique, all Cygnus gauges ignore surface coatings and give only true, accurate measurements. This technique ensures that successive returning echoes precisely match and are thus error-checked before a measurement is displayed. As a result, inspection time and costs are significantly reduced.

The latest Cygnus Underwater is IPX8 rated, which allows continuous underwater operation up to 300 m depth. The feature of “Deep-Coat” mode facilitates measuring through even thicker coatings up to 20 mm thick.

Other features include convenient calibration buttons, echo strength indication and automatic probe recognition (APR), which detects the probe type and optimises the electronics accordingly. The gauge benefits from a large, bright LED display for use in poor visibility conditions. When surface verification is required the Cygnus Underwater can be upgraded to include the topside display options and any length of umbilical cable up to 1000 m long.

This upgrade is straight forward - simply plug in the topside repeater and go! The standard kit includes 2 rechargeable NiMH battery packs, which give over 60 hours’ measuring time and eliminate down-time for battery charging.

With the benefit of all these features, the latest Cygnus Underwater is not just the lightest (950 g) and smallest (235 x 75 mm) underwater gauge available, but also the easiest to use for all typical underwater inspections: ship hulls, semi-sub structures, subsea pipelines, offshore structures, jackets, piers, pilings, etc. All Cygnus thickness gauges carry a 3 year guarantee.
