Cygnus 2+ Hands Free

Ultrasonic Thickness Gauge

A simple yet versatile thickness gauge designed for hands free operation, with its end-mounted display and three measuring modes to measure the wall 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 UTG

  • Multiple-Echo mode for accurate, through-coat measurements as specified by Classification Societies
  • Echo-Echo and Single-Echo modes for heavily corroded metals with a thin or no coating
  • Hands free operation: wrist, waist belt and harness mountable
  • End-Mounted display shows thickness measurements – ideal for rope access or climbing work
  • Front display enables easy gauge setup
  • Deep Coat function ignores coatings up to 20 mm (0.8 inch) thick
  • MSI™ (Measurement Stability Indicator) verifies stable, reliable readings
  • 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 mode 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 (0.8 inch))
  • Single-Echo mode is 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 mode works best for measuring heavily corroded metals through thin coatings of up to 1 mm (0.04 inch) thick, ideal for measuring painted metals with heavy back wall corrosion.

Measurement Stability Indicator (MSI™)

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

Basic Gauge Kit

  • Cygnus 2+ gauge
  • Operating manual
  • Neck strap
  • Accessory pouch, containing; 3 x AA batteries, blue couplant gel.

Kit supplied with Single Element Probe

  • Ultrasonic probe
  • Moulded probe cable
  • 15 mm (or ½ inch) steel test block
  • Spare membranes
  • Membrane key
  • Membrane couplant.

Kit supplied with Twin Element Probe

  • Ultrasonic probe
  • Moulded probe cable.

To compliment our ultrasonic thickness gauges we offer a range of ultrasonic probes. The performance of any ultrasonic thickness gauge relies heavily on the probe and its suitability to the material being measured. Therefore, selecting the right probe is vital. All Cygnus’ 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, used in multiple-echo mode, include replaceable membranes for long life, require no zeroing and have a high linear accuracy.
  • Stainless steel TWIN CRYSTAL probes, used in echo-echo and single-echo modes, have improved measurability on extreme back wall corrosion and pitting.
  • Probes for use with the Cygnus 2+, 4, 4+ and 6+ gauges are fitted with a BNC or Lemo 00 connector.

5 reviews for Cygnus 2+ Hands Free


Dec 02, 2015 9:21 AM

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)
