The IMO 2020 regulation to reduce sulphur oxides ( SOx ) emissions from 3.50% to 0.50% came into force on 1st January 2020. To comply with this, many ship owners and operators have chosen to install an Exhaust Gas Cleaning System - also called"scrubber". However, the wash water from the "scrubber" is highly acid and corrosive. As a result, the discharge has caused extra corrosion in scrubber structures and associated pipework.

Cygnus range of ultrasonic thickness gauges is truly simple-to-use, yet extremely reliable and robust with a 3-year warranty. Employing the Multiple-Echo technique approved by Classification Societies, all Cygnus gauges measure remaining metal thickness accurately without the need to remove coatings. The PLUS models also incorporate Single-Echo measuring mode coupled with the Measurement Stability Indicator (MSI) for testing heavily corroded metals.
