Product Description

Summary
Contact angle refers to the tangent at the gas-liquid interface at the three-phase intersection of gas, liquid and solid. This tangent is at the angle θ between the liquid side and the solid-liquid boundary line. Contact angle measurement is currently the main method for surface performance testing.
SDC-200 standard contact angle measuring instrument is based on the principle of optical imaging, and measures the surface contact angle, wetting performance, surface tension, surface energy and other properties of the sample through image contour analysis.The equipment uses a full-automatic liquid feeding device, which is cost-effective, highly expandable, and fully functional, and can meet various conventional measurement needs. It has been widely used in many colleges and universities and enterprises.
Application
Contact angle measuring instruments are widely used in various industries and fields. In the fields of mobile phone manufacturing, glass manufacturing, surface treatment, materials research, chemical engineering, semiconductor manufacturing, coatings and inks, electronic circuits, textile fibers, medical biology and other fields, contact angle measurement has become an important instrument for evaluating surface performance.
