1. Product Quality and Testing

• Each pH and redox electrode is a high-quality product.

• Every electrode is individually tested and carefully packaged before shipment.

2. Storage Conditions

• Electrodes should be stored in a dry environment at temperatures between -5°C and +30°C.

• Due to the limited shelf-life of pH and redox electrodes, storage longer than 6 months is not recommended.

• All electrodes are supplied with a rinsing cap or storage container to prevent the sensing elements from drying out during transport and storage.

3. Storage Solution

• Electrodes must be stored in a 3 mol/L KCl solution to maintain sensor performance and longevity.

• The storage solution prevents drying of the sensing element and ensures stable measurement characteristics.

4. Conditioning After Dry Storage

• If an electrode has been stored dry for an extended period, it must be conditioned before use.

• Conditioning Procedure:

  1. Immerse the electrode in a 3 mol/L KCl solution.

  2. Allow it to remain submerged for approximately 24 hours.

• This process ensures the electrode is fully hydrated and restores its measurement accuracy.

5. Handling Precautions

• Handle the pH-sensitive glass membrane with care:

  • Avoid skin contact

  • Protect against mechanical damage or scratches

• Ensure that electrical connections and cables are kept clean and dry at all times.

6. Summary of Best Practices

• Store electrodes in a dry room at -5 to +30°C.

• Do not store electrodes longer than 6 months.

• Use the rinsing cap or container provided.

• Store in 3 mol/L KCl solution.

• Condition electrodes after extended dry storage.

• Handle the glass membrane carefully.

• Keep cables and connectors clean and dry.
