Description As we all know, nano-materials science and engineering has become a worldwide hot topic in the study of surface modification of nano-materials, often involves wetting contact angle of this concept. The so-called contact angle refers to the drop on a solid horizontal plane a droplet on a solid surface solid - liquid - gas-phase junction point, the gas - liquid interface and solid - liquid interface of the two tangents when the folder in which the liquid phase the angle formed. SI-CAM2000Y series is to measure the uneven surface contact angle measuring instrument, mainly for hard glasses, contact lenses industry, glass and other circular pipe industry. Japan HOYA optical procurement is this series of instruments.
