Contact Angle Goniometer

Product Introduction

Optical contact angle measuring instrument is an instrument used to measure the contact angle between liquid and solid materials. It is mainly used to characterize the wetting performance of liquid on the surface of solid materials. The image of liquid droplets is obtained through optical imaging, and the contour of the droplet image is fitted by mathematical models using computer software to obtain the contact angle or surface tension. Surface energy calculation and wetting analysis are also performed.

Application Scope

It can be widely applied in materials research, industrial coatings, mobile phone manufacturing, biomedicine, electronic circuits, textile fibers, petroleum extraction, aerospace and other fields.
