描述
LR-SDC-80 水滴角度测试仪
概括
Contact Angle is the tangent line of the gas-liquid interface at the intersection point of gas, 液体和固体. 这条切线在液体和固液边界之间有一个角度. 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, 润湿性, 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.
