2. The electrolytic plate of the hydrogen cup should be plated with platinum, and only the electrode plate plated with platinum will not precipitate heavy metals. The electrode plate of hydrogen spring hydrogen cup is plated with 7 layers of platinum, and the electrolytic plate is not easy to deform and durable for long-term hydrogen production.
3. Choose a water cup with a hydrogen-oxygen separation membrane, because it can block ozone and residual chlorine, and it is more secure to drink and use. Hydrogen spring hydrogen cup adopts ion exchange membrane technology to separate hydrogen and oxygen, and the imported membrane of DuPont 1 17 in the United States is plated with platinum, so that hydrogen and oxygen can be completely separated.
4. Hydrogen production should be stable. At present, many hydrogen-rich water cups can produce hydrogen in 2-3 minutes, but the time is short and the hydrogen production is small. Some cups have few bubbles in a short time (low hydrogen production). The hydrogen concentration in the hydrogen spring hydrogen cup is high, the maximum hydrogen production in 9 minutes is 3700ppb, and the hydrogen dissolution time is long.
5. At present, many products of hydrogen-rich water cups are similar in appearance, but there are no patents or only appearance patents, no water quality test report from national authoritative organizations, and no after-sales maintenance service. Because I dare not go to the national authority for water quality testing, I can't get the relevant water quality certificate. Long-term use of such products is harmful to human body and will cause irreversible damage! So these materials are also indispensable.
