In march 2023 we have bought another one, this is for ourselves in our hire fleet.
We have had several customers and we are also very satisfied with the instrument.
We think the instrument is versatile, multifunctional, robust and intuitive..

Almost a year ago we purchased two Cygnus 1 Ex thickness gauges because of urgent need to provide our customer base UT wall thickness data in ATEX zone 1 and 0. To our knowledge the Cygnus 1 Ex is the only ATEX zone 0 gauge with A-screen for peek-to-peek measurements. We have been using the equipment during in-service storage tank and piping inspection and our operators we very pleased using it. Also the UT thickness data is quite easy to retrieve into excel or csv format for efficient reporting. Last but not least; quality to price ratio is great. Suggestion for improvement is that we would like to see corrosion examination would be made available through a suitable probe set up.
