The machine is qualified, otherwise it can't be produced. Hydrogen-rich water has certain benefits to human body, but the hydrogen-rich water produced by hydrogen-rich water machine rarely meets the standard of real hydrogen-rich water, so it needs to be purchased carefully.

At present, hydrogen machines used in the market can be divided into zero pressure hydrogen machines, low pressure hydrogen machines and high pressure hydrogen machines according to pressure. The zero-pressure hydrogen machine can make more than 200 balls per hour, and the large-scale zero-pressure machine, also known as the large-scale ball filling machine, can fill 2 meters of balls in 3 minutes, and 1 hour can fill 20 balls.
