To celebrate our best-performing product, 3 years since launch, we’re offering a FREE PROBE when you order a Cygnus 1 Ex PRO Anniversary kit! Limited-Time Offer: Ends 31 December 2025. Cygnus 1 Ex PRO Ultrasonic Thickness Gauge (UTG) is designed for taking reliable ultrasonic thickness measurements (UTM) in all hazardous gas Zones (0, 1, 2), coal mines and combustible dust Zones (21, 22).

This anniversary kit includes Cygnus 1 Ex PRO gauge, a Cygnus T5B-Ex Probe and a FREE Cygnus S2C-Ex Probe*

*Only valid when ordering directly from Cygnus Instruments Ltd.

Specifically designed for divers undertaking ultrasonic thickness measurement (UTM) of underwater structures. The Cygnus Underwater diver-held ultrasonic thickness gauge has been built to withstand harsh subsea environments while providing quick and accurate metal thickness measurements through coatings or heavy corrosion. This diver-held thickness gauge is simple to operate using 3 function keys, an intuitive menu and a large LCD display – highly visible, even in low-visibility waters.

Key features of the NEW Cygnus Underwater diver held-gauge include:

• 3 measuring modes for levels of corrosion, various materials and through-coat measurements
• Depth sensor – live depth display providing the diver with an accurate depth indicator
• Live A-Scans aid visual measurement verification
• Extremely Simple-to-Use with 3 function keys and up to 4 screens
• Comprehensive data-logging: linear and grid
• Deep Coat function ignores thick coatings
• RTC (Real Time Clock) for tagging date/time on measurement points
• Auto-set Gain to optimise the probe’s gain settings for optimal performance
• Multiple Echo Mode to verify accurate through-coat measurements as specified by Class Societies
• Measurement Stability Indicator (MSI™) verifies stable and therefore reliable measurements
• Available in STD, PLUS and PRO variants with upgradeable options, e.g. Topside Repeating and Data Logging.

The Cygnus 1 Ex is an Intrinsically Safe Ex gauge, designed for taking reliable thickness measurements in all hazardous gas Zones (0, 1 & 2), coal mines and combustible dust Zones (21, 22). The Cygnus 1 Ex Ultrasonic Thickness Gauge is a rugged, handheld, intrinsically safe instrument designed for taking reliable thickness measurements in Zone 0 Explosive Atmospheres – making it ideal for use in fuel depots, road and vessel tankers, mines, chemical plants, oil and gas, refineries, pipelines, hazardous storage tanks and other hazardous environments. This intrinsically Safe UTG is also certified for safe use in combustible dust Zones (21, 22), such as flour mills, sugar plants, and wood manufacturing.

The Cygnus 4 General Purpose ultrasonic thickness gauge is a small, simple to use and durable through coating digital thickness gauge that uses the multiple-echo measuring mode for accurate and reliable thickness measurement readings up to 20 mm thick.

With its twin shot injection design for harsh environments, simple to use keypad, intuitive menus and large colour LCD display which can be viewed in all lighting conditions - this UT gauge is perfect for general industry use.

Other industries that would benefit from this UT thickness testing device include civil engineering, plant maintenance, shipping, offshore, etc.
