Operating Information:

Remove the protective cap and switch on the unit.

If it will be used for the first time, or haven't been used for a long time, calibrate the unit.

Dip the electrode into the sample solution. Stir gently and wait for a few seconds till the displayed value is stable.

After using, dip the electrode into distilled or deionized water. Stir gently. Then use tissue paper for it to gently absorb the water from the glass bulb. This action must be done very carefully in order to avoid damaging the glass bulb.

When storing the pH meter, switch off the unit, put a few drops of distilled water or deionized water on the spoon inside the cap, to rinse the glass bulb. Then put the cap onto the pH meter.

If the unit cannot be switched on or the display fades, replace all the batteries.



PH meter calibration:

1.the PH value PH electrode immersed in 6.86 (the temperature at 25 oC) standard mixed phosphate buffer solution, gently shake the electrode.

2.with a small screwdriver to adjust the potentiometer until the display value and the standard buffer solution at ambient temperature PH value match.

3.the PH electrode immersed in PH4.01 phosphorus or potassium phthalate standard PH9.18 borax buffer solution, gently shake the electrode.

4.shows the value and the buffer solution PH value should be compared to the range of allowable error.
