Shanghai Guizhen Instrument Equipment Co., Ltd. was established in 2005. Since its establishment, it has been focusing on the development and production of various water quality analysis sensors. Has been solving sensor problems for water professionals around the world. After graduation, the founder of Shanghai Guizheng entered the Shanghai Institute of Ceramics, Chinese Academy of Sciences to engage in the research of new inorganic non-metallic materials and chemical sensors based on new materials. In the mid-1980s, he undertook and participated in the development task of "sterilizable pH sensor", a key project of the Seventh Five-Year Plan issued by the state, and won the second prize of science and technology progress issued by the Chinese Academy of Sciences. Later, I helped Singapore Eutech Instruments to set up a Shanghai representative office to take charge of the marketing and sales in Greater China. During this period, I went to Singapore and other countries for many times to communicate with European and American counterparts on pH, DO, conductivity and other related water analysis instrument skills.
