Contact angle tester is used for the wettability of liquids to solids. It measures the contact angle of liquids to solids, calculates and measures the adhesion of liquids to solids, tension, and surface energy of solids. This instrument is widely used in petroleum, chemical industry, medicine, papermaking, dyestuff and other fields, for scientific research and college teaching. The machine uses imported parts, and at the same time applies micro-control technology to transfer the ingested image into a computer for storage, analysis, and printing. Fast speed, accurate data and easy operation.
Dropper method: static drop method, increase or decrease drop method.
