Contact angle measuring device - TVA100
The TVA100 Top View Analyzer employs the top-view reflection method and measures the contact angle of a liquid on a solid from an above position, making it ideal for measurements in depressions and on concave surfaces, where standard side view is not an option. The contact angle of the drop is determined based on the distance of light spots, reflected at the drop surface. This model uses high-quality components such as the high-quality lens and a high-resolution camera, in order to provide highest possible accuracy. It operates by accurately dispensing the drop, in order to achieve a highly reliable contact angle value. Tests can be conducted quickly, even on multiple liquids, by simply changing the dosing tips.
