LR-SDC-80 Tester kąta kropli wody

Streszczenie

Contact Angle is the tangent line of the gas-liquid interface at the intersection point of gas, płynne i stałe. Ta styczna linia ma kąt między cieczą a granicą ciało stałe-ciecz. The measurement of contact Angle is the main method for surface performance detection nowadays.

LR-SDC-80 basic contact Angle measuring instrument adopts the principle of optical imaging to measure the surface contact Angle, zwilżalność, 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.
