Introduction
JC2000P contact angle measuring instrument is mainly used to measure the contact angle (cleanliness) of liquid on large glass surface, that is, the wettability of liquid to solid, and the contact angle of liquid in external phase. The instrument can measure the contact angle of various liquids to various materials, such as bulk materials, fiber materials, textile materials, etc. Powder samples can also be measured after tableting. At the same time, this series of instruments can measure and calculate surface/interfacial tension, CMC, droplet shape size, and surface free energy.
Characteristics
1. Using computer multimedia technology, the optical system and CCD camera are combined to make the image of the droplet clearly displayed on the computer screen, and the image can be stored for measurement in an instant to avoid measurement failure caused by liquid evaporation.
2. It has three kinds of screenshots: instant freezing, automatic continuous shooting and high-speed photography. Even the volatile liquid can ensure accurate measurement. At the same time, the external tangent is a subjective factor affecting the problem of Zui. The JC2000 series contact angle measuring instrument makes the geometric operation in the software, and the contact angle is no longer artificially judged.
3. Hand-held products, no need to cut products, no separate sample stage.
