Many new types of hydrogen water technologies have emerged in recent years.
Regardless of the method used to create the hydrogen water, the relationships we saw between H2, pH, and the predicted ORP remain the same.
Unfortunately, it is likely that sellers will continue to use the ORP meter as a tool to promote the therapeutic benefits of their particular water for the foreseeable future. Due to the disproportionate influence of pH on redox potential, neutral pH devices will, on average, tend to produce water with less negative ORP values, even if the neutral pH water has the same or higher H2 concentration .
The same 1,6 mg/l H2 water is measured at 9,5 pH -562 mV. Sellers of alkaline water equipment may attempt to increase sales prospects based on the ORP difference (related to the difference in pH) by claiming that the alkaline water has a higher dissolved H2 content or more therapeutic benefit due to its more negative ORP than the pH-neutral water of its competitors.
Although hydrogen infusion machines (HIMs) are often referred to as “pH neutral” devices, the pH of the water produced is typically approximately the same as the pH of the source water, whether or not it was “neutral.”
Armed with an understanding of the concepts presented here, salespeople selling neutral pH hydrogen water products can not only account for the differences in redox values, but more importantly, explain the magnitude of the negative redox values does not have to be an indication of the concentration of dissolved H2.
