TVA100: It is the only instrument in the world to use the top-view reflection method for measuring the contact angle of a liquid on a solid from above. TVA100 determines the contact angle using the radius of curvature of the upper surface of the drop. The innovative measuring method is particularly suitable for measurements in depressions and on concave surfaces where drops cannot be analyzed using the conventional side view.
The measuring head is available as a module for the well-proven KR SS DSA100, DSA30 and Easy Drop instruments and also as an independent portal system for contact-free measurements on large samples.
