--- title: KRÜSS Webinar | Get to know Ayríís description: QC inspections for pre-treated, cleaned or coated surfaces never succeed without prior knowledge – until now. --- [![KRÜSS Scientific - Explore the World of Surface Science](https://visit.kruss-scientific.com/hubfs/blue_logo_kruss-01.svg "KRÜSS Scientific - Explore the World of Surface Science")](https://www.kruss-scientific.com/en) ## Focus Webinar # **How 3D Contact Angle measurement revolution­izes quality control** QC inspections for pre-treated, cleaned or coated surfaces never succeed without prior knowledge – until now. With Ayríís, assessments of drop images or pre- and post-processing for difficult surfaces are a thing of the past. The technologically new 3D Contact Angle method provides an accurate and definite measurement value. Taking a measurement is correspondingly simple: place Ayríís, click, and read the unmistakable result in seconds.
