MEASURING THE HYDROGEN ION CONCENTRATION pH
1. Extract weak ionized alkaline water, strong ionized alkaline water and
weak ionized acidic water respectively from the product, ll the high-
capacity cup with more than 200 mL of the ionized water and then ll
the exclusive cup with
15 mL of the ionized
water.
2. Drop 4 drops of the reagent and lightly swirl the cup.
3. Compare the color of the ion water with the
Hydrogen Ion Concentration (pH) Color table.
4. If the Hydrogen Ion Concentration (pH) is pH 10 or higher, call the service
center and request service (213) 386-9900 / (213) 480-1600.
