4. រៀបចំ

1. Unpack the Electrode: Carefully remove the E-301-QC pH electrode and all accessories from its packaging.
2. ពិនិត្យការខូចខាត៖ Visually inspect the electrode for any signs of physical damage during transit. If any damage is found, do not proceed with setup and contact support.
3. ដោះមួកការពារ៖ Gently remove the protective cap from the electrode tip. You may observe some storage solution around the bulb; this is normal.
4. Rinse Electrode: Rinse the electrode tip thoroughly with distilled or deionized water. Do not wipe the glass bulb, as this can create static charges and scratch the delicate surface.
5. Connect to pH Meter: Connect the electrode's BNC connector to the corresponding input on your pH meter. Ensure a secure connection.
6. Conditioning (if necessary): If the electrode has been stored dry or for an extended period, it may require conditioning. Immerse the electrode tip in a pH 7 buffer solution for at least 30 minutes (or as recommended by your pH meter's manual) before calibration.
7. ការក្រិតតាមខ្នាត៖ Calibrate the electrode with your pH meter using at least two fresh pH buffer solutions (e.g., pH 7.00 and pH 4.00 or pH 10.00). Follow the specific calibration procedure outlined in your pH meter's instruction manual.

5. ប្រតិបត្តិការ

1. រៀបចំ សampលេ៖ ត្រូវប្រាកដថា សample is at a stable temperature. For best results, allow the sample to equilibrate to room temperature if possible.
2. Rinse Electrode: Before each measurement, rinse the electrode tip with distilled or deionized water.
3. Immerse Electrode: Immerse the electrode tip into the sample solution, ensuring that the glass bulb and the reference junction are fully submerged. Stir the solution gently to ensure homogeneity and to remove any air bubbles from the electrode tip.
4. Take Reading: Allow sufficient time for the reading on your pH meter to stabilize. The reading is stable when the value no longer drifts significantly.
5. កត់ត្រាទិន្នន័យ៖ Record the stable pH reading.
6. លាងជម្រះបន្ទាប់ពីប្រើ៖ After each measurement, rinse the electrode thoroughly with distilled or deionized water to prevent cross-contamination and residue buildup.
7. រក្សាទុកឱ្យបានត្រឹមត្រូវ៖ Replace the protective cap and ensure the electrode tip is immersed in the recommended storage solution when not in use. Never store the electrode dry.

6. ការថែទាំ

• ការផ្ទុក៖ Always store the electrode with its protective cap filled with the recommended storage solution (typically a KCL solution or pH 4 buffer). Never store in distilled water, as this can deplete the reference electrolyte.
• ការសម្អាត៖ Regularly clean the electrode. For general cleaning, rinse with distilled water. For stubborn deposits, consult your pH meter's manual or use a mild cleaning solution specifically designed for pH electrodes. Avoid abrasive cleaning methods.
• ប្រេកង់ក្រិត៖ Calibrate your electrode frequently, ideally before each measurement session or at least daily, especially when high accuracy is required or when measuring samples with widely varying pH values.
• Electrolyte Level: For refillable electrodes (if applicable to your specific model), ensure the reference electrolyte level is maintained. The E-301-QC is a composite electrode, so check your specific model's design for refillability.
• អធិការកិច្ច៖ Periodically inspect the glass bulb for scratches, cracks, or deposits. A damaged bulb can lead to inaccurate readings.

7. ការដោះស្រាយបញ្ហា

If you encounter issues with your E-301-QC pH electrode, consider the following common problems and solutions:

• ការអានមិនស្ថិតស្ថេរ៖
  • Ensure the electrode is properly conditioned and calibrated.
  • Check for air bubbles trapped around the glass bulb or reference junction. Gently tap the electrode to dislodge them.
  • Clean the electrode tip to remove any contaminants.
  • ផ្ទៀងផ្ទាត់ថា សample temperature is stable.
  • Ensure the connection to the pH meter is secure.
• ការអានមិនត្រឹមត្រូវ៖
  • Recalibrate the electrode using fresh, unexpired buffer solutions.
  • Ensure the correct buffer values are selected on your pH meter.
  • Check the electrode for physical damage or excessive wear.
  • Verify that the electrode is stored correctly when not in use.
• ពេលវេលាឆ្លើយតបយឺត៖
  • The electrode may need thorough cleaning or re-conditioning.
  • The electrode might be nearing the end of its lifespan.
• No Reading/Error Message:
  • Check the connection cable for damage or loose connections.
  • Ensure the pH meter is functioning correctly (test with another electrode if possible).
  • The electrode may be completely damaged and require replacement.

១.៦. គន្លឹះអ្នកប្រើប្រាស់

• Always Use Fresh Buffers: pH buffer solutions have a limited shelf life once opened. Always use fresh, unexpired buffers for calibration to ensure accuracy.
• Proper Storage is Key: Never allow the electrode's glass bulb to dry out. Always store it in the provided storage solution or a suitable pH 4 buffer.
• ដោះស្រាយដោយប្រុងប្រយ័ត្ន៖ The glass bulb at the tip of the electrode is very delicate. Avoid touching it directly or allowing it to strike hard surfaces.
• សំណងសីតុណ្ហភាព៖ For highly accurate measurements, ensure your pH meter has proper temperature compensation enabled, or manually adjust for temperature variations if your meter requires it.
