Alpha Domestically Manufactured Contact Angle Measuring Instrument
Contact angle is an important measure of solid-surface energy and wettability, used in medicine, semiconductors, material protection, life sciences and other industries. Beituo Science’s domestically developed Alpha contact-angle instrument is designed for industrial users, combining a simple appearance, easy operation and accurate, repeatable data. Manual dispensing and patented software enable one-click measurement to two decimal places. User-friendly software directly controls a high-resolution industrial camera over USB to acquire clear, continuous droplet profiles and extract droplet boundaries effectively.
