Alkaline Pen Calibration Method :

1. Firstly, 6.86 calibration powder is poured into 250ml distilled water or pure water and stirred well. Then turn on the PH meter and put the electrode into the calibration solution.

2. See if the PH pen shows 6.86 or 6.8 in the correction solution of 6.86. If it does not show 6.86 or 6.8, adjust the screw in the screw hole (at the back of the PH meter) with a screwdriver and set the value to 6.86 or 6.8 (0.01 or 0.1 resolution)

3. Find a new cup, fill the same 250 ml of pure water or distilled water. Pour the correction powder of 4.01 into it, mix it well, and put the PH meter which is calibrated just now into the correction solution of 4.01.

4. If 4.01 or 4.0 is displayed,it indicates that the correction is successful, if the display is not 4.01 or 4.0, it needs to be revised in the same way as before.
