LS-SDC-1500 High temperature vacuum contact Angle Tester

Buod

Contact Angle refers to the tangent line of gas-liquid interface made at the intersection point of gas, liquid and solid phases, which is the Angle θ between the liquid side and solid-liquid boundary. The measurement of Contact Angle is the main method of surface performance detection at present.

LR-SDC-1500 high temperature and high vacuum contact Angle measuring instrument is the use of optical imaging principle, through the image profile analysis method to measure the sample surface contact Angle, wettability, pag igting ng interface ng ibabaw, surface energy and other properties, equipment is usually used to detect the surface performance of metal materials,The equipment has high cost performance, stable heating, high vacuum degree, komprehensibong function, and can meet the needs of various metal materials research.
