Scope of application:
The overall inclined contact Angle measuring instrument adopts the principle of optical imaging, and measures the surface contact Angle, wettability energy, surface tension, surface energy, rolling (sliding Angle), forward and backward Angle and hysteresis of the sample surface by means of image profile analysis. In mobile phone manufacturing, glass manufacturing, surface treatment, materials research, chemical engineering, semiconductor manufacturing, paint inks, electronic circuits, textile fibers, medical biology and other fields, contact Angle measurement has become an important instrument to evaluate surface properties.
