Contact Angle Measurement System
Measures how a liquid drop sits on a surface to assess wettability.
Overview
A drop of liquid is placed on the sample and imaged in profile. The angle between the drop and the surface is measured to describe how well the liquid wets the surface.
Applications
- Wettability of coatings and treated surfaces
- Surface cleanliness and adhesion studies
- Surface and interfacial tension by the pendant drop method
