The Attention optical surface tensiometer is widely used in scientific research, development, and quality control of surface and interface studies. It can help you easily and accurately characterize the surface conditions you need to know, saving you valuable time and money. From cutting-edge research to rapid quality control, the Attenson series of optical surface tensiometers make these applications simple and feasible. The multifunctionality of the series products can meet all the product features you need.

Optical surface tensiometers can record droplet images and automatically analyze droplet shapes. The shape of a droplet is a function of the surface tension, gravity, density and humidity differences of different liquid samples, as well as the environmental medium. On solid surfaces, the shape and contact angle of droplets also depend on the properties of the solid, such as surface free energy and morphology. Analyze the obtained image using droplet contour fitting method, and measure the contact angle and surface tension. The surface free energy of materials can be calculated by conducting contact angle tests using several liquids with known surface tension.

As an optical method, the measurement accuracy of an optical surface tension meter depends on the image quality and analysis software. The Attention optical surface tension meter uses a high-quality monochromatic cold LED light source to minimize sample evaporation. High resolution digital lenses, high-quality optical components, and liquid fitting methods ensure image quality.
