Surface contact angle meter 


Contact Angle refers to the tangent line of the gas-liquid interface at the intersection point of gas, liquid and solid. 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, wettability, interfacial tension of table, surface energy, such as performance, equipment cost-effective, comprehensive functions, and can meet the demand of conventional measurement, has been widely used in many colleges and universities institutes and enterprises.

Surface contact angle meter 


Contact Angle measuring instrument is widely used in various industries, in the mobile phone manufacturing, glass manufacturing, surface treatment, material research, chemical and chemical industry, semiconductor manufacturing, paint and ink, electronic circuits, textile fiber, medical biological and other fields, contact Angle measurement has become an important instrument to evaluate the surface performance.
