With 7.0 inch touch screen system, 3 way water quality sensor, 2 way flow sensor for quantified dispensing, 2 stage RO system and EDI module, Center-EDI series ultrapure water system is top choice of high flux ultrapure water for high grade experiments. With tap water inlet, its output ranges from 45 to 90 liters/hour. It can produce deionized water and ultrapure water. The deionized water鈥檚 resistivity is above 10 M惟.cm, and the ultrapure water鈥檚 resistivity absolutely reaches to 18.2M惟.cm. It completely meets the highest grade I standard of ASTM, CAP, CLSI, EP and USP.
