Q: Why Does The Hydrogen Measurement Instrument Display “0” When Measuring Tap Water? Why Does The Hydrogen Measurement Value In Electrolyzed Water Change Over Time?
A: Dear Customer, This Is A Hydrogen Ion Measurement Instrument Specifically Designed To Measure Hydrogen-Rich Water, Not Tap Water. Please Note That This Device Detects Hydrogen Ions. Since Regular Tap Water Does Not Contain Hydrogen Ions, It Will Correctly Display A Value Of “0” When Measured. Hydrogen-Rich Water Is Typically Generated Using A Hydrogen-Rich Cup That Electrolyses Water To Produce Dissolved Hydrogen Ions. Under Normal Conditions, The Hydrogen Content In Water Is Zero, So Seeing A “0” Reading Is Expected. For Accurate Measurement, Please Use This Instrument After Electrolysing Water With The Hydrogen-Rich Cup. However, Due To The High Volatility Of Hydrogen Concentration, The Measurement Value Gradually Decreases Over Time. This Is A Normal Phenomenon.
