LS-1002 Optical Contact Angle Tester

LS-1002 Optical Contact Angle Tester

Summy

Contact Angle refers to the tangent line of the gas-liquid interface at the intersection point of gas, vloeibaar en vast. This tangent line has an Angle between the liquid and the solid-liquid boundary. The measurement of Contact Angle is the main method of surface performance detection nowadays.

Standard contact Angle measurement instrument is to use the principle of optical imaging, image contour analysis way to measure the surface contact Angle, bevochtigbaarheid, grensvlakspanning van de tafel, oppervlakte energie, zoals prestaties, equipment cost-effective, comprehensive functions, and can meet the demand of conventional measurement, wordt op grote schaal gebruikt in veel hogescholen en universiteiten, instituten en bedrijven.
