Nanjing Normal University, abbreviated as "Nanshi", is located in Nanjing, Jiangsu Province, the ancient capital of the Six Dynasties. It is a national "Double * *" construction university jointly established by the Ministry of Education and the Jiangsu Provincial People's Government. As of February 2022, the university has three campuses: Xianlin, Suiyuan, and Zijin. Suiyuan Campus is known as the "most beautiful campus in the East".

Nanjing Normal University had previously purchased other constant temperature water tanks, but due to the long period of time, they were unable to use them and urgently needed to purchase one. Recently, they contacted Chuanheng Instrument. After multiple parameter confirmations, as well as the introduction of physical pictures and videos, the laboratory technicians decided to purchase Chuanheng Instrument's constant temperature water tank, CYSC-05, This device is a 5-liter constant temperature water bath with a temperature range of room temperature -100 and a temperature fluctuation of 0.05, which meets the applicable requirements of the laboratory.
