The Latest Mk5 Range of Ultrasonic Surface Thickness Gages

Winner of the Red Dot Award: Product Design 2015 (Click for more details)

 

Cygnus' latest range of ultrasonic thickness gages includes the standard models employing the Multiple-Echo technique to give accurate through coating thickness measurements. And the Plus+ models feature Multiple-Echo, Echo-Echo and Single-Echo measuring modes - a true 3-in-1 thickness gaging equipment providing versatility for a wider spectrum of applications. For further details on the measuring modes, please see the Technology page.

CygLink software is a Windows based program that is used in conjunction with the gages that have a data logging facility. 

A-Scan and B-Scan displays have been introduced on some models to provide a visualisation of thickness measurements and alternative references.
