Features
Echo-Echo and Single-Echo modes for heavily corroded metals.
Multiple-Echo mode for the most accurate, through-coat measurements (as specified by Classification Societies).
Uses both single and twin crystal transducers.
Deep Coat function ignores coatings up to 0.8 in. (20 mm) thick.
“Hands-free operation”: wrist, waist belt and harness mountable.
MSI™ (Measurement Stability Indicator) verifies stable, reliable readings.
Simple to use menu.
Environmental sealing (water and dustproof) to IP67 – US MIL STD 810G
Highly ruggedized enclosure – shock and impact proof to US MIL STD 810G
One and two point calibration
Can be upgraded to 4+ or 6+ at an additional cost.
Three Versatile Measuring Modes
Multiple-Echo mode uses three (error-checked) back wall echoes to provide the most reliable and accurate remaining thickness measurements. Multiple echo automatically measures through coatings up to 0.8 in. (20 mm)
Echo-Echo mode works best for measuring heavily corroded metals through thin coatings of up to 0.04 in. thick, and is ideal for measuring painted metals with heavy back wall corrosion.
Single-Echo mode is ideal for measuring uncoated metals with heavy front and/or back-wall corrosion. This mode is also effective on a range of cast metals, plastics and composites.
Measurement Stability Indicator (MSI™)
Exclusive to Cygnus, MSI™ ensures that stable and reliable measurements are displayed in Echo‑Echo and Single-Echo modes.

Specifications
Measuring Modes:
Multiple-Echo using 3 echoes to ignore coatings up to 0.8 in. (20 mm) thick

Variety of Cygnus INOX Transducer
Stainless steel SINGLE CRYSTAL transducers, used in multiple-echo mode, include replaceable membranes for long life, require no zeroing and have a high linear accuracy.
Stainless steel TWIN CRYSTAL transducers, used in echo-echo and single-echo modes, have improved measurability on extreme back wall corrosion and pitting.
Transducers for use with the Cygnus 2+, 4, 4+ and 6+ gauges are fitted with a BNC or Lemo 00 connector.
