BXT-80S Manual Contact Angle Tester for Surface Analysis

The contact angle refers to the tangent line of the gas-liquid interface at the intersection point of the gas, liquid, and solid phases. This tangent line forms an angle θ between the liquid side and the solid-liquid boundary. Contact angle measurement is currently the main method for detecting surface properties.

The fully automatic contact angle measuring instrument is a specialized device that uses the shape image analysis method to measure the contact angle, wetting performance, surface tension, surface energy, rolling (sliding angle), forward-backward angle, lagging property, and multi-point automatic intelligent contact angle measurement of the sample surface properties. The device has a high degree of automation and can be combined with an automated production line to achieve online fitting.

The contact angle measuring instrument is widely used in various industries. It has been applied in fields such as mobile phone manufacturing, glass manufacturing, surface treatment, material research, chemical and chemical engineering, semiconductor manufacturing, coatings and inks, electronic circuits, textile fibers, medical and biological research, etc. The contact angle measurement has become an important instrument for evaluating surface properties.
