1. Can replace high-pressure cylinders, double cathode stainless steel electrolytic separation pool, electrolytic nitrogen, boot gas production, flexible and convenient2. Low maintenance costs, normal use only need to add pure water can be used continuously3. The unique anti-reflux device, so that the instrument no reflux phenomenon, three levels of purity to achieve better purification4. Large capacity water storage, so that a water can be up to several days of continuous uninterrupted operation5. The purification tube of the one-time drawing mold reduces the leakage point and more likely protects the reliability of the instrument
