--- title: KRÜSS Webinar | Why test inks don’t tell the full truth description: If you want to know how to ensure your future success in surface free energy measurements, watch this webinar! --- [![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 # **Measuring surface free energy** ## Why test inks don’t tell the full truth One of the most commonly used methods to measure surface free energy is test inks/dyne pens. But they can often lead to inaccurate and unreliable results. Join the Focus Webinar with Dr. Youssef Akil to ensure your future success in SFE measurements!
