FAQ: Cygnus 6+ – Ultrasonic Thickness Gauge

What is the key technology of the Cygnus 6+?

It utilizes the Multiple-Echo (ME) technique, which allows it to measure material thickness through paint or thick coatings while ignoring the coating thickness itself.

What is the main advantage of the Multiple-Echo technique?

It eliminates the need to remove coatings (like paint) for accurate measurement, saving significant time and reducing surface damage during corrosion inspection.

What is the “+ ” in the model name?

The “+” usually indicates that the gauge is also capable of Single-Echo (SE) and Echo-Echo (EE) modes in addition to the standard ME mode, providing versatility.
