All Cygnus gauges are calibrated for Steel when they are manufactured and the calibration can be adjusted to suit the type of material under test.  Certificates of calibration are issued at the factory.  The gauges can be returned for recalibration at the customer’s request and in accordance with their own quality requirements.  This is usually every 12 months when the equipment can be tested, checked and recalibrated using equipment traceable to national standards.”

The European Standard BS EN 15317 'Characterization and verification of ultrasonic thickness measuring equipment' recommends all gauges to be subject to an annual Performance Check to ensure correct operation.  All new Cygnus gauges are manufactured in accordance with this standard.

ROVworld Lda can arrange professional servicing and calibration, in our workshop, as required.
