Introduction: This machine is a new CAM7.1TM measurement software, special features such as automatic contact angle measurement, surface measurement, reference line aid and coordinate display are added. It is used to measure and analyze the contact angle of liquid on solid surface, the surface tension of liquid, droplet geometry, solid surface energy and its components, etc., to achieve the pro-/hydrophobicity analysis, wettability analysis, cleanliness of solid surface. Testing, evaluation of treatment effects, and analysis of processes such as competition, absorption, absorption and spreading of liquids. Widely used in chemical, pharmaceutical, food, electronics, printing and dyeing and spraying and other fields of testing and research. Features: 1. The whole machine adopts aluminum alloy bottom plate with exclusive design of multi-dimensional precision mechanical positioning slide, coordinated control sample table, sample adding system and imaging system 2. The sample adding device adopts peristaltic pump to add liquid and is suitable for solid surface hydrophobic/hydrophobicity analysis and cleanliness detection. It is easy to operate. 3. Image capture using high acquisition speed CMOS camera and continuous zoom lens with low distortion rate, clear and undistorted images 4. Backlight source adopts continuously adjustable brightness and uniform LED cold light source technology to ensure clear outline of droplets 5. The software provides a variety of analysis methods such as volume angle method, volume high method, five-point curve fitting method, automatic image analysis method, and hanging drop fitting method. 6. The contact angle of the liquid on the solid surface can be tested. The left and right contact angles can be tested and compared separately. The software automatically obtains the average contact angle value. 7. The software has a curved surface correction function to test the contact angle of convex and concave surfaces, spherical surfaces, and rough irregular surfaces. 8. The picture can be directly measured without saving, any three-point circle can be used to find the contact angle value, and the contact angle value can also be automatically analyzed. 9. Not only can measure the liquid surface tension, but also can calculate the outline size (including height, width, contact diameter, etc.) of the droplet 10. Software provides a variety of surface free energy estimation models for polar solids, non-polar solids, low-energy solids, high-energy solids and other surfaces 11. The software has multiple shooting modes such as single shot, interval shooting, continuous capture and video shooting to meet various testing needs 12. The software has the functions of coordinate display, brightness adjustment, baseline assistance and fast memory auto trigger, which can help the analysis of the image accurately and clearly 13. The software has a powerful database management function, save, print, raw data query and re-analysis can be achieved Technical Parameters: Liquid surface tension Measurement method: hanging drop method Measurement results: surface tension, droplet geometry, droplet contact point coordinates display Measurement range: 0.01 to 1000mN/m Measurement accuracy: ±0.1% (relative to the measured value) Measurement resolution: 0.001mN/m Solid surface free energy Estimation method: Fowkes one-fluid method, OWRK two-fluid method, Wu harmonic mean two-liquid method, LW-AB three-fluid method Estimated results: Solid surface free energy and its polar, non-polar components 3.
