Contact angle measuring instrument

It is mainly used to measure the contact angle of liquid to solid, that is, the wettability of liquid to solid. The instrument can measure the contact angle of various liquids to various materials. The instrument plays a very important role in scientific research and production in petroleum, printing and dyeing, medicine, spraying, beneficiation and other industries.

Product Description

Equipment principle:


When the droplet reaches equilibrium on the surface of the solid, it is at the junction of gas, liquid and solid,
The angle between gas-liquid interface and liquid-solid interface is called contact angle, which is the main means to characterize the wettability of materials.





Product features:



Video capture system

Injection system

Control system

3D mobile sample table

Analysis software


Product function:




Stable: modular design concept, aviation grade material, independent research and development 

of integrated chip circuit control, stable and reliable, and ensure quality from the source.

Good: LED cold light source + industrial professional camera + imported industrial camera to ensure the best imaging effect.

Full: eight functions, including solid-liquid dynamic and static contact angle measurement and meter interface
Tension analysis, surface free energy measurement, adhesion work analysis and other functions.

Standard: eight test methods and fitting methods. Select the most appropriate test method and fitting method 

according to the sample state and contact angle to ensure the accuracy of the data. The original differential ellipse /

circle method provides 3D morphology method and local contour test method for rough samples.

Variable: the dynamic contact angle can be measured according to the real-time change of droplets; 

It can monitor the equipment status in real time; Optional accessories can be provided according to customer needs.
