Measuring the pH Level (Ion Concentration)
Engli
sh
After the Alkaline Ionizer has been installed or after it has not
been used for a prolonged period (generally, a week or more),
be absolutely sure to measure the pH level, and check that it
is within the “pH standard” before using the Alkaline Ionizer.
Remember to measure the pH level periodically
(at least once a month).
What is the pH level (ion concentration)?
The pH level indicates the degree of alkalinity, neutrality or acidity of
water (aqueous solutions), and stands for “hydrogen ion exponent.”

What to have ready: pH test kit (supplied accessory)
Procedure for measurement
1
Put 2 drops of pH test liquid in to the
test tube.
(The pH cannot be determined accurately any amount
other than 2 drops.)

Test tube
2
Run alkaline ion water or weak acidic water for approximately
10 seconds, then keep the sample water in a cup.
(In order to obtain a stable pH value.)
3
Put the sample water into the test tube.
Fill up to the line.
4
Under the enough light,
compare the result with the
pH Chart.
pH Chart
pH standard
Alkaline 4 (Strongly Alkaline) 9.5 ~ 10.5
Alkaline 3
9.0 ~ 10.0
Alkaline 2
8.5 ~ 9.5
Alkaline 1
8.0 ~ 9.0
Weak Acidic
5.0 ~ 6.5
Important
The color of the test water will change as time passes. Compare its pH level against the pH Chart right away.
The pH level cannot be measured accurately using litmus paper available on the market. Be absolutely sure to measure it using the pH test kit.
To dispose of the pH test liquid, dilute it with water before pouring it down the drain.
The pH test liquid and pH Chart will become discolored if they are exposed to sunlight so store them in a dark place.
Note
The pH test kit is for measuring the rough pH level.
The main components of the reagent are ethanol, methyl red, bromothymol blue and phenolphthalein.
Depending on the water quality, the water treated by the Alkaline Ionizer may not be within the pH
standard range or the alkaline ion water may not be alkaline (a liquid which appears blue or dark
blue may change to a green or yellow color). If this is the case, take the following action.
Use “pH Fine Adjustment” to set the alkalinity or slight acidity to “Stronger”. (P. EN24)
In addition, when the unpurifi ed water is measured, the color of the test water may diff er from
what is on the pH Chart (due to the eff ects of carbonic acid or other components in the water).
If the pH level is high, change the water quality to weak alkaline or mix the water with purifi ed water before using it.
When the cartridge is new (about a week old), the pH level may be somewhat higher: this is normal and does not indicate any trouble.
