Contact angle tester can be tested as follows: 1) The contact angle on the plane, curved and non-horizontal surfaces, the repeatability error of less than 0.1 ° 2) through the surface energy of the substrate (solid surface energy or surface tension of the liquid) to calculate polar and acid-base distribution, degree of dispersion between miscibility between unipolar unipolar acid and alkali component 3) liquid / liquid, liquid / solid miscibility 4) Wetting envelop 5) uptake and evaporation 6) the humidity, and saturation vapor pressure of the contact angle and surface energy 7) oil removal efficiency between the oil and the oil or oil and metal between 8) surfactant efficacy 9) Characterization of wetting and contact angle by dehumidifying efficiency characteristic relaxation 10) contact angle changes in the relationship between relaxation and wetting / dehumidification between 11) Surface energy and surface composition changes and changes in the relationship between surface modification technical indicators: Measuring method: Washburn penetration measurement range: 0-330mbar Accuracy: 0.16 mbar Temperature range: room temperature quartz tube size: 10mm diameter droplets Dongguan angle measurement, diameter 8mm / 6mm Host Dimension: 295X240X260mm Power: 220V drops angle measurement where, 20W Specifications: Measuring method: Washburn penetration measurement range: 0-330mbar Accuracy: 0.16mbar temperature range: room temperature quartz tube dimensions: diameter 10mm, inner diameter of 8mm / 6mm Host Dimension: 295X240X260mm Power: 220V, 20W Dongguan droplets angle, angle of water droplets, ShengDing instrument precision from Dongguan ShengDing Instruments Limited.
