The SDA-101 is an advanced testing instrument designed to measure and analyse contact angles on surfaces. Contact angle measurements are an empirical tool for understanding the wetting, between a liquid and a substrate, both for research as well as for quality control. In brief, the instrument automatically applies a liquid drop on a test surface and then records the spreading of the drop (absorption/adsorption) over time. The surface can be either absorbent or homogeneous. Examples of applications include: paper, cardboard, plastic foil, wood, glass, steel, etc. It precisely measures and analyses drop-shaped liquids on various surfaces. With its high precision and user-friendly features, the SDA101 is ideal for your application.
