Contact Angle instrument is an important experimental tool used to measure the contact Angle of liquid on solid surface. Its development has gone through many stages. In the purchase process of the contact Angle instrument, it is necessary to consider the classification of the instrument, optical imaging system, host design and contact Angle analysis technology.

1, the contact Angle instrument can be classified according to its contact Angle optical system and the contact Angle analysis method in the software. At present, the main categories are Angle measuring instrument, standard contact Angle instrument and advanced contact Angle instrument. Goniometer is an earlier instrument, from simple Angle measurement to the development of models using CCD and software. The standard contact Angle meter uses CCD and software system, not only stays in the simple Angle measurement stage, but also adopts curve analysis method. The advanced contact Angle meter tries to directly analyze the contact Angle by eliminating the influence factors such as the surface tension of the liquid through advanced optical system and analysis technology. Such classification facilitates rational analysis and the selection of appropriate instruments.

2, optical imaging system docking antenna software analysis is crucial. Although the computer system is advanced, the design of the optical system directly affects the image quality. In general, the optical system is composed of a lens and CCD with a certain magnification. Good imaging results should be shown as a clear background, a clear foreground, and even a sense of realism, such as metal.

3. The host design of the contact Angle instrument is also one of the key factors to be considered when purchasing. The stability of the host, ease of operation, focusing accuracy, and matching with the software design are all critical. In addition, the shape and volume of the sample that can be tested should be considered, otherwise the test may not be completed. Different operational requirements may require different designs of the console, which must be confirmed with the vendor’s sales engineer.

4, contact Angle analysis technology is very important. The data required for the actual application is the most critical, so it is necessary to ensure that the contact Angle analysis technology provided by the supplier meets the requirements. Discussing such technologies with suppliers during the purchase process and understanding how they meet real needs is crucial.

To sum up, the purchase of contact Angle instrument needs to consider its classification, optical imaging system, host design and contact Angle analysis technology. Only by taking these factors into account can we choose the contact Angle instrument that is most suitable for the actual needs.
