DL/T864-201 Silicone Rubber Insulator Surface Wettability Measurement, Static Contact Angle Rubber Testing Equipment
Application:
This machine is an entry-level static contact angle analyzer that is affordable and easy to operate. It measures the contact angle of a liquid on a solid surface based on the principle of optical image analysis. It can also estimate the surface energy of a solid and its component values. It is widely used in the analysis of surface treatment effect and cleanliness of spraying, coating, glass, aluminum foil, electronic components and cleaning industries.
Standards:
- DL/T864-201
- IEC 62073, IECTS 62073-2016
