Underwater Mk5 UTG KIT | 300m Rated Ultrasonic Thickness Gauge for Divers & Subsea Inspections

The Underwater Mk5 UTG KIT is a professional ultrasonic thickness gauge designed for divers carrying out underwater thickness measurement (UTM) on marine and offshore structures. Built to perform in the harshest subsea environments, this diver-held gauge delivers fast, reliable, and highly accurate metal thickness readings – even through heavy corrosion and protective coatings.

Featuring a depth rating of 300 m, the Underwater Mk5 UTG KIT is ideal for inspections of ship hulls, offshore oil and gas platforms, subsea pipelines, storage tanks, canal locks, and civil engineering structures. Its large, high-visibility LCD screen with intuitive 3-key operation ensures clear measurements even in low-visibility conditions.

With three selectable measuring modes (Multiple-Echo, Single-Echo, and Echo-Echo), divers can tackle a wide range of inspection scenarios. The exclusive Measurement Stability Indicator (MSI) verifies stable and reliable results, while the built-in depth sensor provides live diver depth readings.

The kit also includes advanced data logging, allowing divers to record up to 5,000 measurements with A-scans and depth information, which can be easily reviewed using CygLink software for reporting and analysis.

Key Features of the Underwater Mk5 UTG KIT:

• Depth rated to 300 m for demanding subsea operations

• Multiple-Echo mode for accurate measurements through coatings up to 20 mm

• Echo-Echo and Single-Echo modes for heavily corroded metals and composites

• Live A-Scan display for verification of readings

• Comprehensive linear and grid data logging with auto-log function

• 2.4” sunlight-readable colour display

• Rechargeable Ni-MH battery with 8+ hours continuous operation

• Shock and impact tested to MIL-STD-810G standards

The Underwater Mk5 UTG KIT is trusted worldwide by commercial divers, marine surveyors, and offshore operators for UWILD and IWS class surveys. With upgradeable variants (STD, PLUS, PRO), it provides long-term value and adaptability for a wide range of underwater inspection needs.
