Trade in any subsea UT thickness gauge—diver held or ROV mounted, any brand, any age, any condition—to upgrade to Cygnus Underwater, featuring automatic data-logging, high visibility LED display for low light conditions, live A Scan, and integrated depth sensor.

Designed for subsea corrosion surveys, the Cygnus Underwater Diver Held Gauge delivers fast, accurate thickness measurements through coatings and heavy corrosion, reducing diver workload and bottom time. A high-visibility LED display ensures clear readings in low-light, turbid water, while simple operation keeps divers focused. Multiple Echo, Live A-scan, and Measurement Stability Indicator (MSI) provide reliable, automatically logged results, reducing errors and re-dives.

Benefits include:

No coating removal;
Less probe stabilisation;
Shorter and faster testing;
Reduced struggle with currents and surges;
Improved diver safety.

Rugged, shock proof, and double O ring sealed, Cygnus Underwater is engineered for confined spaces, turbulent harbours, and demanding offshore conditions.

Cygnus 1 Ex: Intrinsically Safe UTM for Hazardous Marine Areas

In hazardous marine environments - offshore platforms, tankers, and fuel storage terminals - inspections must be carried out safely without ignition risk or operational disruption. Cygnus 1 Ex is the world’s only intrinsically safe ultrasonic thickness gauge (UTG) fully certified by ATEX, IECEx and UKEX for Zone 0 – the highest rating. It supports in-service thickness measurement in explosive atmospheres Zones 0–2, without shutdowns or hot work permits.

When paired with Cygnus’ High Temperature Ex Probe, engineers can inspect live steam systems, hot vessels and elevated temperature pipework without interrupting production.

Cygnus 1 Ex achieves the highest level of intrinsic safety with:

Low energy circuitry - eliminates sparks;
Anti static housing - avoids charge accumulation;
Voltage clamping - controls output;
Redundant safety electronics;
Fail safe battery and thermal protection.

Cygnus’ Multiple Echo technique measures metal thickness through coatings without removal, reducing preparation time, preserving protection, and improving inspection efficiency.

A Unified Approach to Marine Asset Integrity

Cygnus Underwater and Cygnus 1 Ex form a comprehensive ultrasonic inspection toolkit supporting:
Increased safety;
Lower maintenance costs;
Regulatory compliance;
Extended asset life.

Cygnus Instruments remains a trusted partner for shipowners, ports, surveyors, and marine engineers seeking accurate, durable inspection technology above and below the waterline.
