Water Contact Angle Tester_Surface Treatment Effect Analyzer

Введение продукта

Applications

Widely used in the analysis of surface treatment effects and cleanliness detection in industries such as spraying, coating, glass, aluminum foil, electronic components, and cleaning.

Features

Uniquely designed precision mechanical structure for multi-dimensional coordinated control of the sample stage, sample loading system, and imaging system.
The main frame is made of lightweight and high-strength aluminum alloy through CNC machining after professional design, with a plastic-sprayed surface.
The sample loading device uses a gear-rack and threaded lead screw to drive the syringe for liquid loading, with multiple specifications of liquid syringes available as options.
A patented sample lifting and translation combination platform that enables large-range movement without any shaking or tilting.
A camera and continuously zoomable lens, combined with a precision focusing positioning stage, enabling long-distance clear focusing.
Cold light source technology to ensure clear droplet contours.
Real-time video monitoring of the test area, capable of instant freezing and continuous capture of sample image information, with adjustable capture cycles.
The software provides various professional measurement and calculation methods, suitable for the analysis of multiple types of solid surfaces and droplet shapes.
The software can calculate contact angle values in multiple ways, and the left and right contact angles can be calculated and compared separately to achieve more accurate test results.
The software supports saving and importing images for re-analysis, as well as printing test data.
