Thickness gauge with ultrasonic technology

Fast facts

Cygnus thickness gauges - precision, reliability and confidence in every measurement
We at ZRS are proud resellers of Cygnus Instruments - the world leader in ultrasonic thickness measurement. With proven Multiple-Echo technology, you get accurate measurements through paint, rust and coatings - without having to grind off the protective layer. This saves time, preserves the material and reduces the risk of errors.

The technique works by recording multiple ultrasonic echoes inside the material, making it possible to measure the true wall thickness even when the surface is painted or corroded.

Whether you're working underwater, in an industrial environment or inspecting tanks, pipes and structures, there's a model to suit your needs. Cygnus combines British engineering, robust construction and intuitive operation - all so you can trust every reading, every time.

ZRS offers advice, service and support - with a focus on long-term value and technical security. Together we help you choose the right meter for the job.
