Wetting measurements in depressions and on concave surfaces
The TVA100B Top View Analyzer is the only instrument in the world to use the top-view distance method for measuring the contact angle of a liquid on a solid from above. The innovative measuring method is particularly suitable for measurements in depressions and on concave surfaces where drops cannot be analyzed using the usual side view.
A further strength of the TVA100B lies in the especially high precision in the range of very low contact angles, which makes it an ideal tool for assessing the cleanliness of glass, for example.
