Introduction: WTF Micro Analytical Laboratory Ultra Pure Water Machine is suitable for HPLC, TOC, PCR, AAS, ICP, ICP-MS, IVF, cell culture, genetic engineering, amino acid analysis, DNA recombination research, ultra trace and trace inorganic materials And organic analysis. Features: 1. Microcomputer automatic control design, LCD large screen Chinese color LCD screen display, equipment running status at a glance, human-machine dialogue function is complete; 2. The system produces three kinds of water at the same time, namely pure drinking water, RO pure water and UP ultra pure water; 3. The system adopts the unique double membrane process design to effectively extend the service life of consumables and improve the water quality; 4. The system adopts two-stage reverse osmosis process design, which is especially suitable for high-salt water (such as northern China) influent water source, reducing equipment operating costs; 5. The system has functions such as power-on self-test, automatic circulation flushing, water shortage alarm, automatic power-off of power failure, automatic shutdown of full water, and ultra-low voltage protection; 6. The system has UP ultra-pure water emission setting function, consumables failure voice alarm and replacement prompt function; 7. The system has pure water conductivity, UP ultra-pure water resistivity, total organic carbon (TOC) online detection display function; 8. The system adopts a built-in double-tank design (20L reverse osmosis inter-stage water tank and 20L secondary reverse osmosis pure water tank) to completely ensure the water consumption; 9. Built-in WATER large-capacity integrated dual-channel injection pretreatment + three-channel purification column system, longer life; 10. The system has 0-9999ml regular quantitative water withdrawal function; 11. The system has the function of timely real-time voice broadcasting, which can better reflect the humanized design of the machine; 12. The system is equipped with a reverse osmosis pressure monitoring table, which can determine the operating pressure and fouling degree of the reverse osmosis membrane through pressure at any time. 13. The system has a historical data storage query function, can effectively and accurately record and query the previous water intake time (year/month/day/hour/minute), water withdrawal (ml) and water quality (water conductivity and ultrapure water resistance Rate) and other historical data; 14. The system has regular on/off function, the user can arbitrarily set the startup or shutdown time, at the same time with the current date display and clock display and set functions; 15. The system has a second-level PIN password protection. It can set a power-on password and a user operation password. The equipment management rights and usage rights are separated to prevent unrelated personnel from operating. 16. Can be equipped with UV dual wavelength 185nm and 254nm UV digestion system (optional); 17. Can be equipped with original 0.22μm terminal capsule type heat source filter imported from Germany (optional); 18.RS485 interface networking function, with remote transmission computer data processing save and print, remote software failure judgment Technical Parameters: 1.
