Contact angle measuring instrument

surfacecameraCCD

It is mainly used to measure the contact angle of liquid to solid, that is, the wettability of liquid to solid. It can also be used to measure The external phase is the contact angle of the liquid. This instrument can measure the contact angle of various liquids on various materials. In the fields of mobile phone manufacturing, glass manufacturing, surface treatment, material research, chemical engineering, semiconductor manufacturing, coating ink, electronic circuit, textile fiber, medical biology and other fields, contact angle measurement has become an important instrument for evaluating surface properties. Equipment principle 1. The contact angle measuring instrument is mainly composed of light source, injection unit, acquisition system and analysis software. The equipment adopts the principle of optical imaging. The light source adopts dense LED cold light design, which emits light evenly, cleans the image and has a long service life; 2. The injection unit adopts the manual knob type to drip accurately, the drip is stable and the precision is high; the acquisition system adopts a miniature industrial grade microscope, CCD camera, stable shooting, clear images, real and reliable, the lens adopts industrial grade configuration, and the imaging is free from distortion; 3. The analysis software is powerful, with one-button automatic fitting ability and fitting method, which can meet the fitting of various droplet shapes.
