Portable contact angle testerSuitable for measuring the contact angle or wetting/spreading degree of liquids on various solid surfaces, the measurement is not limited by the size or morphology of the sample or the location.

The contact angle refers to the tangent line of the gas-liquid interface at the intersection of gas, liquid, and solid phases, which is the angle between the liquid side and the solid-liquid boundary line.Portable contact angle testerBy utilizing the principle of optical imaging, the image of liquid droplets formed after falling onto a solid surface is captured by a camera, and the contour of the droplets is analyzed using image processing techniques to calculate the contact angle.

The portable contact angle tester mainly consists of the following parts:

1. Light source: Provides illumination to ensure that the camera can capture clear images of droplets.

2. Injection unit: used to drop liquid onto a solid surface to form droplets.

3. Acquisition system: including a camera and image processing software, used to capture and analyze droplet images.

4. Analysis software: used to process collected image data and calculate parameters such as contact angle.

This device is used to measure parameters such as the contact angle between liquid and solid surfaces. When using, it is necessary to follow certain operating steps and precautions to ensure the accuracy of measurement results and the normal operation of the instrument.
