With 7.0 inch touch screen system, 3 way water quality sensor, 2 way flow sensor for quantified dispensing, and 2 stage RO system, Center series deionized water system is top choice of high flux deionized water for general grade experiments. With tap water inlet, its output ranges from 45 to 90 liters/hour. It can produce 2nd stage RO water and deionized water. The 2nd stage RO water’s conductivity can stay 1-5μs/cm, and the deionized water’s resistivity absolutely reaches to 10MΩ.cm. It completely meets the requirements of general chemical or biological experiments for pure water.
