As a leading manufacturer of plasma surface treatment systems, Keylink offers advanced contact angle measurement equipment to help you verify surface cleanliness, validate plasma treatment effects, and ensure optimal adhesion for your materials.
Contact angle meters, also known as tensiometers or goniometers, are widely used across various industries to measure the contact angle of a liquid on a solid surface, providing insights into wettability, surface energy, and adhesion properties. Key industries employing these instruments include materials science, coatings, pharmaceuticals, electronics, and automotive manufacturing.
Contact angle meters are often used to evaluate the effectiveness of plasma treatment by measuring the wettability of a surface after treatment. Plasma treatment modifies the surface properties of materials, and contact angle measurements provide a quantitative assessment of these changes, indicating the degree of hydrophilicity or hydrophobicity.
The basic principle of a contact angle meter involves placing a small droplet of the liquid onto the solid surface and then using a camera and analysis software to measure the angle formed by the droplet where it meets the surface. Optical tensiometers typically have a camera, a dispenser for creating the droplet, a sample stage, and a light source.
The contact angle (θ) is the angle formed between the liquid-solid interface and the liquid-vapor interface at the droplet’s edge. It indicates:

Keylink’s goniometers come with the CA V2.0 software, providing a comprehensive analysis tool for material professionals.
The software supports both static and dynamic contact angle measurement. You can perform static analyses using methods like the sessile drop method or dynamic analyses to measure advancing and receding angles. This includes contact angle hysteresis, which is closely related to a surface’s wetting properties.
Our system offers multiple calculation methods, including Circle, Ellipse, three-point, and five-point fitting, with an automatic fitting feature for accurate, ms-level one-key measurement. This reduces manual error and speeds up your quality control process.
The software can calculate surface energy from contact angle using a pre-installed database of 37 liquids and multiple estimation methods like Fowkes, OWRK, and Acid-Base Theory. You can obtain detailed data on dispersion, polar forces, and hydrogen bonding to better understand your material’s properties. This makes it ideal for those who want precise surface energy calculation from contact angle data.

The primary difference is the dropping mechanism. The CA01 is a manual model where the operator controls liquid dispensing, ideal for basic tests. The CA02 is an automatic model with a dedicated auto-dispensing system for more consistent, high-volume testing in manufacturing environments.
Yes, our equipment is compatible with Windows 10 64-bit systems. We recommend a computer with an I3 2.0GHz or higher CPU and at least 4G of RAM for optimal performance.
The software can measure dynamic contact angles, including advancing and receding angles. It also calculates contact angle hysteresis, which reflects the difficulty of a droplet rolling off a surface. This is achieved by either adding/subtracting liquid or using a tilting plate method.
Yes, our software includes a dedicated module for surface energy calculation from contact angle. It uses various theoretical methods and a pre-installed liquid database to estimate surface free energy and its components, which cannot be measured directly.
The angle of contact definition refers to the angle formed at the junction of a liquid, solid, and air interface. For example, what is angle of contact in surface tension is the angle that determines whether a liquid wets a solid. What is contact angle of water is a commonly asked question: water typically shows a contact angle of ~0° on clean glass (complete wetting) and higher on hydrophobic coatings.
