1. The contact angle measuring range: 0 ... 180o2 accuracy:. ± 0.1o3 * surface / interfacial tension measurement range:. 0.01 ... 2000mN / m4 accuracy:. 0.01 mN / m5 * source: single-wavelength LED cold light source 6. * wavelength range: 450 ± 10 nm7 Maximum sample size: Unlimited x 95 x 180 mm main purpose of measuring the contact angle are you doing? Measurement method can be used to calculate the surface tension measuring the contact angle. But my clients are judged by the contact angle of the hydrophilic high-temperature vacuum contact angle iron, in order to confirm the effect of surface treatment or cleaning. Measuring the contact angle have a special machine. China-made imports of all. Prices are not the same. You can Dongguan Sheng Ding contact angle precision instrument. The measuring instrument has the following characteristics: 1, can be any measure, not as a fixed contact angle measuring instrument is restricted machine size. 2, dropping small drops of water temperature, the minimum reached 0.1ul, reducing the influence of gravity, high-temperature contact angle measurements was slightly uneven and will not be affected. 3 vacuum furnace in contact angle measurements, because the machine is small, can be measured on a non-planar objects such as circular and the like. 4, automatic measurements, built-in camera to take pictures of water droplets dripping the whole process, you can manually measure. High-temperature heating contact angle measurement, Sheng Ding instrument (online consultation), high temperature provided by the Dongguan City Ding Sheng Precision Instrument Company. 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.
