With LED controlling system, single stage RO system, 1 pump, and portable TDS/conductivity test pen, Basic-Q series deionized water system is basic choice of deionized water for general grade experiments.

With tap water inlet, its output ranges from 15 to 45 liters/hour. It can produce single stage RO water and deionized water. The single stage RO water´s ion rejection rate is more than 97%, and the deionized water´s resistivity is more than 13MΩ.cm, near to17.5MΩ.cm. It completely meets the requirements of general chemical or biological experiments for pure water.
