Dynamic contact angle measurement for dynamic contact angle between solid and liquid, Wilhelmy plate method using contact angle measurement research, the United States and out of the liquid contact angle measurement by platinum pieces, creating a tension ─ displacement hysteresis curve, through the positioning of the curve, using computer control, the measured data can be stored, printed, curve analysis can find the dynamic contact angle. It can be widely for scientific research and production departments to detect a variety of liquid surface tension in petroleum, chemical, electronics, metallurgy, water, medicine, paper, printing, teaching, quality supervision and other technical parameters with a contact angle measuring range: 0 180 ° contact angle measurement accuracy: +/- 0.1 ° 2, the contact angle test methods: sessile drop method 3, the contact angle analysis: Manually measuring the level of the contact angle, manual ramp measurement, the width and height measurements, artificial tangent method 4,2x fixed multiple HD microscope 5, 6 digital CMOS camera, video recording / playback 7, instant screenshots standard contact angle drip angle _ _ Kono contact angle provided by the Dongguan City Ding Sheng Precision Instrument Company.
