Bluelab pH Probe KCl Storage Solution

Bluelab pH Probe KCl Storage Solution – The perfect solution to store and hydrate your pH probes or pens. It is imperative to store your instrument using this solution, to ensure faster and more accurate response times and a longer probe lifespan.

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.

De-ionized, distilled, Pure or RO (reverse osmosis) water should never be used to store or hydrate a pH probe or pen. Pure water will affect the chemistry of your reference solution inside of your pH probe, and this will cause the probe or pen to fail prematurely.
