Dynamic Interface Tension TesterDeveloped and manufactured by Beijing Hako, there are usually two testing methods: one is the shape image analysis method; The second method is the weighing method The latter is commonly referred to as a wetting balance or a permeation contact angle meter But currently, the most widely used method for direct and accurate measurement is still the shape image analysis method The principle of the shape image analysis method is to drop liquid droplets onto the surface of a solid sample, obtain the shape image of the droplets through a microscope lens and camera, and then use digital image processing and some algorithms to calculate the contact angle of the droplets in the image
