On the afternoon of January 14, 2019, the general manager of HYDRO-BIOS Apparatebau GmbH, Mr. Julian made a special visit to Dawan. General manager Howard Chang and Mr. Julian had a two-hour technical exchange and business cooperation exchange.

As a senior technician in the marine equipment manufacturing industry, Mr. Julian has a profound knowledge in the design and processing of electronic circuits and machinery. From a professional point of view, Mr. Julian unreservedly provided a lot of valuable experience and suggestions for the production process of the CTD of Daowan.

Mr. Julian's visit has provided great help to the development of Daowan , and made us more confident to complete the seemingly simple but very deep marine equipment.

During the visit, Mr. Julian also expressed the intention of HYDRO-BIOS and Daowan to cooperate in technology. Mr. Julian hopes to drive the multi-channel water sample collector of HYDRO-BIOS Apparatebau GmbH through Daowan’s CTD instrument.The agreement communicated in detail to determine the feasibility of cooperation. It is believed that in the near future, domestic users will be able to purchase multi-channel water sample collectors with higher cost performance (German quality, Chinese prices).
