Typical experiment
Notice：
Calibration pH sensor:
Case: Measure the pH value of orange juice
The physical and chemical properties determination of water
Measurement of soil acid and alkaline
To explore reaction of carbon dioxide with clarify whitewash
Properties difference of different concentration solutions (pH)
Volatilization of concentrated ammonia and dissolution of ammonia
Note: pH calibration fluid (pH buffer), can use the solution by known pH
value, or self configuration, or buy it in the chemical reagents store
Rinse the electrodes before each measurement, do not use absorbent paper
to wipe the glass ball of electrode, this may lead the electrode does not work,
you'd better rinse the electrodes by measured solution
In order to keep the exchange process of electrode ion occurred, the glass
ball should be stored in the saturated KCl solution, If the electrode was
drying, immersed in saturated KCl solution for 24 hours, make it back to the
common state.
Don't storeage the electrodes in distilled water or deionized water, this will
lead saturated solution around the electrode moving
Avoid use in the extreme acid solution or extreme temperature value
Open ，click ，choose“pH sensor”，click“Calibration”；
The electrode is rinsed with distilled water, and wipe with an absorbent
paper，sock it in pH4.0 calibration fluid，when the value(on the left-lower
corner) is stability, click (at the back of the )；
High-end value calibration by pH9.18 calibration fluid，repeat the previous
step；
Remove electrodes, rinse the electrodes with distilled water and wipe with an
absorbent paper;
