It can simply test the aluminum tank, the aluminum foil packing hydrogen water, the water element bar (hydrogen rich water bar), the hydrogen rich water cup, the hydrogen water generator, the electrolytic reduction water generator, the hydrogen content in the natural water
To the measured liquid slowly adding reagent, if the water contains hydrogen, such as 0.5ppm, so every drop of water will instantly transparent color is blue, and then will immediately restore transparent color, so in 5 drops of water can recover from blue into the transparent color. But when sixth drops were dropped, the blue water could no longer be restored to a transparent color, indicating that the hydrogen content of the liquid was 0.5ppm
