Water Droplet Angle Tester Is Used To Measure The Wettability Of Liquids On Solids

The definition of the water droplet Angle is in solid and liquid. The contact Angle between the gas-liquid phase interface and the solid-liquid phase interface at the gas-liquid phase interface is a measure of the humidity of a solid surface. It is measured using most of the liquid droplets of the adherent. A low contact Angle indicates a high humidity (hydrophilic) surface that is easy to adhere. A high contact water droplet Angle indicates that the surface shows hydrophobicity, has heavy organic contamination on the surface, or has poor surface adhesion. The contact Angle of the liquid in contact with a flat solid surface is determined by the end point of the water droplet curve at the liquid-solid-gas junction and the contact point on the solid surface to analyze the surface cleanliness. The contact Angle is a scale indicating the humidity of the solid surface. It is measured using most of the adherent droplets. A low contact Angle indicates high humidity (hydrophilic or hydrophobic) and low surface energy.

The contact Angle tester is used to measure the wettability of liquids on solids. By measuring the contact Angle of the liquid on the solid, it can calculate the surface free energy of the solid and the surface tension of the liquid and other indicators. This instrumentWater droplet angle tester , dyes, etc., for scientific research and teaching purposes. Our factory's series of contact Angle testers are independently developed.

Product features
1. According to international standards, conduct standard design of the instrument structure (injection needle: 0.51mm, liquid injection accuracy: 0.1ul)
Second, use the measurement methods in accordance with the standards. For instance, the width-height method should be adopted for temperatures below 20°, and the elliptical method for temperatures between 20° and 120°. This is to prevent excessive structural deviations during testing due to incorrect methods. At present, manufacturers in Guangdong only use the ring method for testing, which has a large deviation and is not standardized.
Third, it is equipped with tests for curved surface angles, concave and convex angles, forward and backward angles, to prevent the instrument from being unable to test due to subsequent product updates by customers. For example, the subsequent touch screen may take on a curved shape.
Fourth, it adopts industrial light sources and precise algorithms to avoid the diffusion of light source wavelengths, and at the same time, it can accurately test angles ranging from 2 to 10 degrees. Currently, the instruments on the market cannot collect images below 10° due to unstable light wavelengths, and thus cannot be tested.
V. Introduction to Instrument Functions
This instrument is manufactured with modern technology. It is equipped with an advanced dedicated CMOS digital camera, a high-resolution continuous zoom microscope, and a high-brightness and stable industrial light source. It is also paired with a three-dimensional sample stage, allowing for movement in various directions such as up and down, left and right, and front and back on the workbench. Achieve micro-injection and precise up and down, left and right movement. At the same time, a telescopic rod structure workbench has been designed, which can adapt to the occasions where the material thickness of different users increases. The instrument frame can be adjusted appropriately according to the size of the sample, which expands the application range of the instrument. The software, in combination with the correction function, enables the results of multiple tests to be saved simultaneously in the same report, allowing users to better manage the material data. This instrument is elegantly designed, easy to operate and meets the needs of users. It is suitable for users in various industries who need to measure contact angles.
