The TVA100 Top View Analyzer (photo) measures the contact angle of liquids using the image of light spots that are mirrored by the curved surface of the drop. Contact angles in the lower range (down to 1.5 deg), which in the past has been difficult to approach, can be measured with precision by this technique. The view from above makes wetting inhomogeneities immediately visible. Surface energy measurements can be carried out thanks to the insensitive precision dosing unit with a wide range of liquids. — Krüss GmbH, Hamburg, Germany
