• రీఫిల్ చేయదగినది: Allows for replenishment of the reference electrolyte, prolonging the electrode's lifespan and maintaining performance.
• Ag/AgCl Reference Cell: Ensures stable and reliable potential readings.
• Made in United States: Manufactured to high quality standards.
• కాంపాక్ట్ కొలతలు: Package dimensions are 10.9 x 4.1 x 2.2 inches, with an item weight of 6.38 ounces.

సెటప్

1. అన్‌ప్యాకింగ్: ఎలక్ట్రోడ్‌ను దాని ప్యాకేజింగ్ నుండి జాగ్రత్తగా తొలగించండి. కనిపించే ఏదైనా నష్టం కోసం తనిఖీ చేయండి.
2. Electrolyte Filling (if necessary): This electrode is refillable. If the electrolyte level is low, open the fill hole (usually indicated by an "OPEN" arrow or cap) and carefully add the appropriate reference electrolyte solution (e.g., 3M KCl) until the level is just below the fill hole. Close the fill hole securely.
3. ప్రక్షాళన: Rinse the electrode tip with distilled or deionized water to remove any storage solution. Do not wipe the glass bulb, as this can create static charges.
4. కండిషనింగ్: For optimal performance, soak the electrode in a pH 7 buffer solution for at least 30 minutes (or longer, up to several hours) before first use or after prolonged dry storage. This rehydrates the glass membrane.
5. Connecting to Meter: Connect the electrode's BNC connector (or other specified connector type) to the corresponding input on your pH meter. Ensure a secure connection.
6. క్రమాంకనం: Calibrate your pH meter with the electrode using at least two, preferably three, fresh pH buffer solutions (e.g., pH 4.01, 7.00, and 10.00). Follow your pH meter's specific calibration procedure.

1. తయారీ: Ensure the electrode is properly conditioned and calibrated.
2. Sampకొలత:
   • Rinse the electrode with distilled or deionized water between sampలెస్.
   • ఎలక్ట్రోడ్ కొనను s లో ముంచండిample solution, ensuring the glass bulb and junction are fully submerged.
   • Stir the solution gently to ensure homogeneity and faster response.
   • Allow the reading to stabilize before recording the pH value. Stability is typically indicated by a stable reading on the pH meter for a few seconds.
3. ఉష్ణోగ్రత పరిహారం: If your pH meter has automatic temperature compensation (ATC), ensure the temperature probe is also immersed in the sample. If not, manually input the sample temperature into the meter.

నిర్వహణ

• ప్రక్షాళన: Always rinse the electrode with distilled or deionized water after each use to prevent sample residue buildup.
• నిల్వ: Store the electrode in a dedicated electrode storage solution or pH 4 buffer solution. Never store the electrode dry or in distilled water, as this will dehydrate the glass membrane and deplete the reference electrolyte. Ensure the storage cap is filled with solution and securely placed over the electrode tip.
• Electrolyte Refill: Regularly check the level of the reference electrolyte. If it is low, refill with the recommended solution (e.g., 3M KCl) as described in the Setup section.
• శుభ్రపరచడం:
  • సాధారణ శుభ్రపరచడం: For routine cleaning, soak the electrode in a mild detergent solution for 15-30 minutes, then rinse thoroughly with distilled water.
  • ప్రోటీన్ నిక్షేపాలు: Soak in a 1% pepsin solution in 0.1M HCl for 1 hour.
  • Inorganic Deposits: Soak in a 0.1M HCl or 0.1M HNO3 solution for 15-30 minutes.
  • Grease/Oil Films: Rinse with a mild solvent (e.g., ethanol or isopropanol), then immediately rinse with distilled water.

  After any cleaning procedure, recondition the electrode in pH 7 buffer for at least 30 minutes before use.
• క్రమాంకనం ఫ్రీక్వెన్సీ: Calibrate your electrode regularly, ideally before each measurement session or at least daily, especially when high accuracy is required or when measuring samples with extreme pH values.
