About us

Cygnus Instruments Ltd

Cygnus Instruments Ltd is the leading manufacturer of multiple-echo ultrasonic thickness gauges used for measuring remaining metal thickness without the need to remove protective coatings. Following extensive customer engagement, Cygnus have developed a new range of ultrasonic thickness gauges which still use the well established multiple-echo technique but incorporated within the PLUS models is single-echo and echo-echo measuring modes using twin crystal probes. Single-echo and echo-echo can assist in obtaining measurements in areas of extreme corrosion or back wall pitting.

Cygnus has a range of measuring instruments which include:

Surface thickness gauges: ATEX approved intrinsically safe gauge for use in Zone 0, Zone 1 hazardous areas and requires no plant shutdown or hot work permit; hands free gauge designed for climbing or rope access work where safe hands free operation is paramount; general purpose gauge with A-scan display and sequential data logging; and a more advanced gauge with A-scan and B-scan display, comprehensive data logging, manual gain control, Bluetooth, and much more.

Underwater thickness gauges: diver wrist-mountable data logging gauge with a large bright AMOLED A-scan display; ROV mountable unit depth rated to 2,000 meters with optional probe handling solutions; and the original RINA approved divers hand-held gauge depth rated to 300 meters.

And an ultrasonic hatch cover leak detector for testing weather tightness of cargo hold hatch covers and door seals.
