Bead height / width method using equations to fit the round shape Kono summarize the contact angle of droplets SL100B, thus accounting of the contact angle. Since this approach assumes that the droplets (cross-section) is part of a circle shape, so its scope is limited to spherical or near to spherical droplets. The contact angle due to the influence of gravity, strictly standard optical contact angle SL100, the shape of the droplets are contrary ball: The degree of the breach increases with the increase of the volume of the droplets; at the same volume, the proportion of the more liquid large, surface tension smaller, contrary to the greater fluctuation. Under normal circumstances, on volume of less than 5 microliters of water droplets, which suffered the impact of gravity on the shape is considered small enough to be negligible, this approach accounts available at the moment. Speaking after the literature measuring the height and width of the droplet contact angle of approach to accounting that is the round could have been the easiest method to use. The above mentioned method Conic round Act would have been included, because the circle of a quadratic equation only exception. Dynamic contact angle measurement for dynamic contact angle between solid and liquid, using Wilhelmy plate method, and out of the liquid through the platinum film, thereby forming a hysteresis tension ─ displacement curve, then by positioning the curve, using computer control, The measured data storage and printing, for curve analysis to determine the dynamic contact angle. It can be widely for scientific research and production sectors in the field of petroleum, chemical, electronics, metallurgy, water, medicine, paper, printing, teaching, quality supervision, such as testing a variety of liquid surface tension manually type contact angle SL100C, contact angle, Kono Ltd. provided by the Dongguan City Sheng Ding precision instruments.
