The system has the function of real-time voice alarm and replacement prompt for consumables failure, and the consumables failure limit can be freely set between 1-18.25M Ω. cm according to the actual needs of customers; Once the consumable value drops to the limit, the system will simultaneously provide voice and subtitle prompts for consumable replacement information to avoid mistakenly using unqualified water for experiments.

12. Adopting a built-in quick installation integrated dual channel injection molding pre-treatment and integrated dual channel injection molding ultra purification column system, the service life is longer;

13. The system has a timed and quantitative water intake function of 0-9999ml, and can set the water intake quantitative value according to needs;

14. The system has a historical data storage and query function of up to 5 years, which can effectively and accurately record all data within the past 5 years, and query historical data such as water intake time (year/month/day/hour/minute), water intake volume (ml), and water intake quality;

15. The system is equipped with a 30 liter antibacterial conical water tank, made of HDPE polyethylene material, with a double-layer box design and standard 0.22 μ m composite air filter. The bottom of the conical bucket is equipped with a drainage valve to drain the water stored in the tank, ensuring thorough cleaning and effectively avoiding secondary pollution of water quality;

16. The system has a timed power on/off function, allowing users to freely set the power on or off time. It also has the function of displaying the current date and clock, as well as setting the time;

17. The system is equipped with a second level PIN password protection, which can set a startup password and a user operation password. The device management and usage rights are separated to prevent unauthorized personnel from operating.
