Measure and adjust the pH level of water
What to have ready: pH test kit (supplied accessory)
Put 2 drops of pH test liquid in to the
test tube.
The pH cannot be determined accurately any amount
other than 2 drops.
If the test water is placed before the pH test liquid is added, the two
liquids may not be evenly mixed, leading to incorrect measurement.
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 level)
Put the sample water into the test tube.
If some of the test water is first collected in a glass and then
poured into the test tube, it will be easier to align the level with
the line inside the test tube.
So long as the water inside the test tube is within 5 mm above
or below the line, no problems will be posed in the pH level
measurement: there is no need to adjust the level until it comes
up to the exact level of the line.
Under the enough light,
compare the result with the
pH Chart.
The color of the test water will change as time passes.
Compare its pH level against the pH Chart right away.

If a new cartridge is used (for about 1 week), the pH level will be slightly higher, but this phenomenon is normal.
For the determination of raw water, the color of test water will be different from that in the pH Chart due to the
influence of the various ingredients in the water.
Use of commercial litmus paper will lead to incorrect test.
Notes
Procedure for measurement
Pour the water until
it is near the line
inside the test tube.
