Cygnus 1 Intrinsically Safe
Multiple Echo Ultrasonic Thickness Gauge
The Cygnus 1 Intrinsically Safe is a rugged, shock-proof multiple echo ultrasonic surface thickness gauge designed for safely measuring metal thickness to determine wastage or corrosion in potentially explosive environments. By using multiple echo technology the metal thickness gauge measurements are error checked using 3 return echoes to provide repeatable, reliable results.
Supplied ready to use in a protective carry case with 2 rechargeable batteries, the Cygnus 1 Intrinsically Safe can achieve up to 10 hours of continuous testing before recharge is necessary.
Cygnus Instruments builds all of its equipment in the UK using only genuine and original parts and components – including Lemo® Connectors and Peli® Cases.

It is an old gauge (intrinsically safe) but keeps working well.
I love this machine. Even for corroded areas, it has proven to be reliable. I like the fact that you can change the Db settings to enable better penetration and sensitivity on corroded surfaces. We have to use Ex certified equipment in the offshore oil and gas industry which makes this UTM gauge ideal. I would give it an 8/10. (Only because it’s design makes it awkward to use when the operator is using Rope Access as a means of carrying out the inspection.)
This will certainly be useful in the inspection and maintenance of our shipping industry.
I really like this piece of equipment, very reliable, I do recommended to others, specially to use on oil and gas plants, I been using my for over 10 years, right now I’m looking forward to purchase a next one, probably I will go with same type since not really hard with calibration, is true a little awkward to use on such position, like hanging or under pipelines. But not a big deal.
