Cygnus 2+ Hands Free

Ultrasonic Thickness Tester

Designed for hands free operation, this simple yet versatile ultrasonic thickness tester has an end-mounted display and three measuring modes for measuring thickness of a variety of materials (including plastics) and metals of any level of corrosion and pitting.

Key features of the Cygnus 2+ Hands Free ultrasonic thickness tester include:

  • Multiple-Echo for accurate through-coat measurements, as specified by Classification Societies
  • Echo-Echo and Single-Echo for heavily corroded metals with a thin or no coating
  • Hands free operation – wrist, waist belt and harness mountable
  • End-mounted display for thickness measurements, making it ideal for rope access and climbing applications
  • Front display enabling easy set-up of ultrasonic thickness tester
  • Deep Coat mode that ignores coatings up to 20 mm thick
  • MSI™ helps verify stable and reliable measurements
  • Intuitive easy to use menu
  • Extremely rugged enclosure – shock and impact proof to US MIL STD 810G
  • Environmental sealing (water and dust proof) to IP67 – US MIL STD 810G.
  • Uses single and twin crystal probes
  • One and two point calibration
  • Can be upgraded to 4+ or 6+ at an additional cost.

Three Versatile Measuring Modes

  • Multiple-Echo: Uses three error checked back wall echoes to provide the most reliable and accurate remaining thickness measurements, with no need to remove coatings (up to 20 mm thick).
  • Single-Echo: Ideal for measuring uncoated metals with heavy front and/or back-wall corrosion. Also effective on a range of cast metals, plastics and composites.
  • Echo-Echo: Works best for measuring heavily corroded metals through thin coatings of up to 1 mm thick, making it ideal for measuring painted metals with heavy back wall corrosion.

MSI™ (Measurement Stability Indicator)

Exclusive to Cygnus, MSI™ ensures stable and therefore, reliable measurements are displayed in Echo‑Echo and Single-Echo modes.

To compliment Cygnus’ range of ultrasonic thickness testers we offer a range of portable UTM probes. The performance of any ultrasonic thickness tester relies heavily on the probe and its suitability to the material being tested. Therefore, selecting the right probe is vital.

All Cygnus’ portable UTM probes are made from stainless steel and have a hard wear face or a wear membrane to protect the probe.

Variety of Cygnus INOX Probes

  • Stainless steel Single Crystal probes: Uses multiple-echo mode, includes replaceable membranes for long life, require no zeroing and have a high linear accuracy.
  • Stainless steel Twin Crystal probes: Uses echo-echo and single-echo modes and have improved measurability on extreme back wall corrosion and pitting.
  • Probes for use with the Cygnus 2+, 4, 4+ and 6+ testers are fitted with a BNC or Lemo 00 connector.

We were asked to test the New Cygnus UTM Instruments 2+ and 4+, using their single and twin crystals probes.

Tests carried out in our premises on specially prepared samples and in real working conditions on a 15 years old dry cargo ship of 10.000 M.Tns.
Both instruments, apart they are well designed, they proved to be fast and accurate.

The gauging confirmation through the new measuring experience of MSI System, was a pleasant surprise.

User-friendly with high analysis full coloured LCD screen and very easy menu.

The strong tight case together with the strong cable and its twin lemo locking connector give the immediate impression of the unit being very rugged.

Believe it or not in the company that I belong to, we have an old one Cygnus 2 (single crystal) since 1990 or less, we compare to other devises that we have and confiability of Cygnus is incredible, there are certain surface that other can not measure. And our Cygnus has not the possibility to calibrate but when we test with the test block always is correct.

Haven’t had it long (9 months) but seems reliable and robust, despite being an older model (MK3)
