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 method is particularly suitable for measurements in depressions and on concave surfaces where drops cannot be analyzed using the usual side view.
TVA100B has high precision in the range of very low contact angles, which makes it an ideal tool for assessing the cleanliness of glass, for example.
