Water droplet angle tester

Water droplet angle measuring instrumentUsing the method of analyzing external images for testing, the droplet's external image is obtained through a microscope lens and camera, and then the droplet angle is calculated using digital image processing and algorithms. This device can measure the contact angle of various liquids with different materials, including block materials, fiber materials, textile materials, etc. Powder samples can also be measured after compression. At the same time, this series of instruments can also measure and calculate surface tension/interfacial tension CMC、 Droplet shape, size, surface free energy, etc.

Water droplet angle measuring instrumentIt is a professional scientific research and industrial application instrument used to accurately measure the contact angle between liquid and solid surfaces, as well as the surface tension of liquids. This device is widely used in scientific research in fields such as petroleum, chemical, pharmaceutical, power, printing, and education.
