PH Pen Storage Solution

Add a few drops in the cap of your PH pen, replace the cap and store upright.

  • Rinse the PH probe under running water after use
  • Place a few drops of PH solution in the cap and replace it
  • Keep the pen upright for storage to preven soution leaking out

This storage solution is the best way to keep your electrode from your PH meter from deteriorating over time.


R35.00 VAT Incl.

pH Storage Solution is used to keep pH probe moist which will maximize electrode performance and extend life of electrode.

Directly after use and before a period of storage rinse your pH electrode under running water after every use. Then place a few drops of pH Storage Solution in cap and close cap.

Please keep pH Pen upright to ensure that storage solution does not leak out.

How a pH meter works.  The glass electrode is the most important in reading pH, and consists of an electrical wire made of silver submerged in potassium chloride, surrounded by a special silica and metallic salt-coated conductive tube. The reference electrode is usually made of the same material as the glass electrode, but its tube lacks any special conductive coating.

When submerged in a solution, hydrogen ions will migrate towards the conductive glass electrode and replace some of the metal ions in the coating. This creates a small voltage that the silver electrode is able to pick up, which is then passed on to the voltmeter, which converts the signal into a pH reading. The reference electrode acts as a baseline measurement, and completes the electrical circuit.
