LS-SDC-1000 Large platform optical contact Angle Tester

Streszczenie

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.

LS-SDC-1000 type platform contact Angle measurement instrument is using the principle of optical imaging, image contour analysis way to measure the surface contact Angle, zwilżalność, napięcie międzyfazowe stołu, energia powierzchniowa, takie jak wydajność, equipment cost-effective, kompleksowe funkcje, high test precision and can meet the large size products, such as TV flat glass and other special products with conventional sample measurement needs.
