Shengding Optical Contact Angle Measurement Instrument Test Guidance

About this manual

The document provides testing guidance for the optical contact angle measurement instrument produced by Shengding. It covers procedures for evaluating super‑hydrophilic and super‑hydrophobic surfaces, including software toolbar usage and image capture.

For contact angles below 40°, the circle method is selected by clicking the “圆” icon; for angles above 40°, the ellipse method (“椭” icon) is used. Users can perform automatic fitting by pressing the “2” key or the toolbar icon when the baseline is level, otherwise manual fitting is performed by selecting three points and clicking the fitting icon. This manual is written in Chinese.
