Máy đo góc tiếp xúc GA-1101
Bản tóm tắt
Contact Angle is the tangent line of the gas-liquid interface at the intersection point of gas, liquid and solid. This tangent line has an Angle between the liquid and the solid-liquid boundary. The measurement of contact Angle is the main method for surface performance detection nowadays.
GA-1101 basic contact Angle measuring instrument adopts the principle of optical imaging to measure the surface contact Angle, wettability, surface energy and other properties of the sample by means of image profile analysis. The equipment has high cost performance, comprehensive functions and can meet the requirements of conventional sample surface wettability measurement.
