The 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, SDC500 contact angle measurement, in order to confirm the effect of surface treatment or cleaning. Measuring the contact angle have a special machine Domestic 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, the contact angle, which could be measured, not as a fixed contact angle measuring instrument is restricted machine size. 2, dropping small drops of water, SDC300 contact angle measurement, the minimum reached 0.1ul, reducing the influence of gravity, the measurement was slightly uneven and will not be affected. 3, due to the small size of the machine, can be measured on a non-flat objects like 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 expansion and contraction of the visual apparatus is a test sample using a parallel light beam heated, SDC200 contact angle measurement, by changes in sample projected on the background to the real-time observation and firing the expansion and contraction of the equipment parameters of the sample requirements for ceramic samples: the unfired powder, dry pressed into Φ2-25 mm, a height of not more than 10mm film. Firing system: according to the requirements of the development of the firing system, the maximum temperature does not exceed 1600oC, 1000oC the following heating rate of not more than 30oC / min, 1000oC over not more than 10oC / min. SDC80 contact angle measurement, Sheng Ding instrument (online consultation), the contact angle 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.
