ISO 15989 ASTM D5946 Contact Angle Goniometer for Plastics Film and Sheeting Corona Treated Polymer Film
Principle:
As shown above, the contact angle measuring instrument is mainly composed of five major parts: light source, injection unit, sample tables, acquisition system and analysis software, and the equipment adopts the principle of optical imaging.
Light source adopts intensive LED cold light design, uniform luminescence, image cleaning and long life;
Injection unit adopts high-precision syringe pump for liquid feeding, controlled by software with quantitative and fixed speed, stable drops and accuracy up to 0.01 µl;
Sample tables adopts three-dimensional manual fine adjustment platform, flexible operation, accurate positioning, sample stage can be customized according to the actual sample size
The acquisition system adopts black and white imported CCD camera, with stable shooting, clear and reliable images, the lens adopts German industrial grade imported configuration, adjustable 0.7-4.5 times magnification, imaging without distortion and distortion;
The analysis software is powerful and has the ability of one-key automatic fitting, with the most leading international fitting method, to meet the accurate fitting of various droplet forms.
