Bluelab pH Probe KCl Storage Solution

Bluelab pH Probe KCl Storage Solution

R320.00

Protect your pH probe and keep its readings sharp. Bluelab pH Probe KCl Storage Solution is the correct way to store and hydrate your pH probes and pens — keeping the glass electrode conditioned so it responds faster, reads more accurately and lasts longer.

  • Faster, accurate readings: proper storage ensures quicker response times and reliable measurements.
  • Longer probe life: keeps the electrode hydrated to extend its working lifespan.
  • Purpose-made: a potassium chloride (KCl) solution formulated specifically for pH probe storage.
  • A must for every grower: it’s imperative to store pH instruments in this solution, not water.

Important: never use de-ionised, distilled, pure or RO (reverse osmosis) water to store or hydrate a pH probe or pen — pure water alters the chemistry of the probe’s internal reference solution and damages it. Use only KCl storage solution.

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.
