Mr. Howard Chang introduced the development concept and current technical level of Dawan Company to the leaders in detail. Daowan is committed to "breaking foreign monopolies and creating national brands". Since its inception, it has always followed the principle of "independent and controllable key technologies" and fully utilized its own funds for technological development. At present, Daowan's pressure sensors are purchased from domestic brands; temperature sensor core components (thermistors) are purchased from domestic brands, and then packaged by Daowan; conductivity sensors are completely manufactured by Daowan; measurement circuits are completely designed and produced by Daowan; The system is completely built by Daowan. The localization rate of Dawan CTD's complete machine can reach up to 99%, which is not subject to foreign technical blockade. The accuracy of Daowan ’s core sensors has reached or exceeded the first-class level of the national metrological standards and national marine survey specifications. Leaders expressed their high appreciation for Daowan's ability to make high-precision CTD as a private enterprise.

Qingdao Daowan Technology Co., Ltd. was established in October 2016 and its registered place is Qingdao Ocean Sensor Industrial Technology Research Institute (Qingdao Blue Silicon Valley). The company focuses on independent technology research and development, product manufacturing and technical services of high-precision CTD, especially the research and development of products suitable for extreme water environment (deep sea, polar region). Dao Wan is willing to contribute to China's polar ocean scientific research!

Daowan will make persistent efforts and move forward steadily, striving to do a good job in Chinese high-precision CTD!
