Automatic contact angle measurement, mainly used to measure liquid contact angle on solids, namely liquid to solid wettability. The instrument can measure a variety of liquid contact angle on various materials. The contact angle analysis: θ / 2 method, automatic analysis method 2, the captured image method: single shot, continuous interval shooting (slow memory), continuous shooting (fast memory) 3, antenna test range then: 0 <θ <180 ° 4, test resolution: 0.01 ° 5, test accuracy: technical questions about measuring static water contact angle? Static contact angle measured the film, because the film always get uneven, resulting in a film, the biggest difference between the measured data can to ten degrees, a sample to be measured for a long time, ask the experts what methods can facilitate the film flatten C201 automatic contact angle meter, or what instruments can be used to prepare a glass slide, put a small nail above US Kono drop angle, the film side with double-sided adhesive type automatic liquid contact angle meter, paste nails placed on a glass slide contact angle test of time directly to the small liquid drops in projecting position, to facilitate the observation, also can relatively flat membrane stretched US Kono drop angle, United States (online consultation), The contact angle provided by the Dongguan City Ding Sheng Precision Instrument Co., Dongguan Sheng Ding Precision Instrument Co., Ltd. (www.dgshengding.com) (www.dgshengding.com) Dongguan, Guangdong, dedicated instrumentation leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs. Sheng Ding instrument in leadership with the staff warmly welcome all inquiries negotiations to create Shengding instrument better future.
