Proper setup is crucial for optimal performance of your Sentix H pH Electrode. Follow these steps:

1. Paketin açılması: Elektrodu ambalajından dikkatlice çıkarın. Gözle görülür bir hasar olup olmadığını kontrol edin.
2. Storage Solution Removal: The electrode tip is typically protected by a cap containing a storage solution. Remove this cap. Do not discard the cap or solution, as it is needed for storage.
3. Durulama: Rinse the electrode tip thoroughly with distilled or deionized water to remove any residual storage solution. Gently blot dry with a lint-free tissue.
4. Connecting to Meter: Connect the S7 plug head of the electrode to the corresponding S7 input port on your compatible pH meter. Ensure a secure connection.
5. Pre-conditioning (if necessary): For new electrodes or those that have been stored dry, immerse the electrode tip in a suitable electrode storage solution or pH 7 buffer for at least 30 minutes to an hour before first use.

Kullanım Talimatları

The Sentix H electrode is optimized for high alkaline solutions. Adhere to the following operational guidelines:

• Kalibrasyon: Always calibrate the electrode with fresh pH buffer solutions (e.g., pH 7.00 and pH 10.00 or pH 12.00 for high alkaline range) before each measurement session or as recommended by your pH meter's manual. Ensure the buffers are at the same temperature as your samples.
• Sample Immersion: Immerse the electrode tip fully into the sample solution, ensuring the liquid junction is completely submerged. Stir the sample gently to ensure homogeneity and stable readings.
• Reading Stability: Allow sufficient time for the reading to stabilize. This electrode features special glass membranes and an adapted diaphragm technique for optimal accuracy, but stabilization time can vary depending on the sampley.
• Rinsing Between SampŞunlar: Rinse the electrode thoroughly with distilled or deionized water between each sample measurement to prevent cross-contamination.
• Sıcaklık Telafisi: Utilize the temperature compensation feature of your pH meter, or ensure samples and buffers are at a consistent temperature.

Bakım

Regular maintenance extends the lifespan and ensures the accuracy of your electrode:

• Temizlik:
  • Genel Temizlik: Her kullanımdan sonra elektrodu damıtılmış veya iyonize edilmiş suyla iyice durulayın.
  • Protein Birikimleri: For protein contamination, soak the electrode in a pepsin/HCl solution for several hours.
  • İnorganik Tortular: For inorganic deposits, soak in a 0.1 M HCl or 0.1 M HNO3 solution for 15-30 minutes.
  • Grease/Oil: For grease or oil, clean with a mild detergent solution, then rinse thoroughly.
• Depolamak: Always store the electrode with its tip immersed in a suitable electrode storage solution (e.g., 3M KCl solution) or the original storage solution provided. Elektrodu asla kuru halde veya dam distilled suda saklamayın.
• Elektrolit Seviyesi: Ensure the electrolyte level in the electrode is maintained. Refill if necessary according to the electrode's specific requirements.
• Denetleme: Periodically inspect the glass bulb and junction for cracks, scratches, or blockages.
