With 5.0 inch touch screen system, 3 way water quality sensors, 2 way flow sensors to achieve quantified dispensing, built-in 1 buffer water tank, 3 pumps, and 2 stage RO system, its output ranges from 12 to 24 liters/hour with tap water inlet. Moreover, it equips the remote portable dispenser and 50 liters tank as standard configuration.
It can produce 2 kinds of pure water- deionized water and ultrapure water. And the third kind of pure water-2nd stage RO water is optional.
The 2nd stage RO water’s conductivity can stay 1-5μs/cm. The deionized water’s resistivity is above 16MΩ.cm, and the ultrapure water’s resistivity absolutely reaches to 18.2MΩ.cm. It completely meets the highest grade I standard of ASTM, CAP, CLSI, EP and USP.
