2 സുരക്ഷാ വിവരങ്ങൾ

Always handle the pH electrode with care. The glass bulb at the tip is fragile. Avoid dropping or subjecting the electrode to mechanical shock. Do not allow the electrode to dry out, as this can permanently damage the sensor. Always store the electrode in its protective cap with appropriate storage solution.

3. ഉൽപ്പന്നം കഴിഞ്ഞുview

The WD-35811-71 electrode is an all-in-one design, meaning it integrates both the pH sensing element and the reference electrode into a single probe. Its epoxy body provides enhanced durability, making it suitable for general laboratory and field use. The sealed design minimizes maintenance requirements.

4.1 അൺപാക്കിംഗ്

• ഇലക്ട്രോഡ് അതിന്റെ പാക്കേജിംഗിൽ നിന്ന് ശ്രദ്ധാപൂർവ്വം നീക്കം ചെയ്യുക.
• Inspect the electrode for any visible damage. If damage is present, contact your supplier immediately.

4.2 Initial Conditioning

• Remove the protective storage cap from the electrode tip. The cap typically contains a storage solution to keep the glass bulb hydrated.
• Rinse the electrode tip with distilled or deionized water. Do not wipe the glass bulb, as this can create static charges and affect readings.
• For optimal performance, condition the electrode by immersing the tip in pH 7 buffer solution for at least 30 minutes before first use.

4.3 Connecting to a pH Meter

• Ensure your Oakton pH 6+ meter is turned off.
• Carefully plug the electrode connector into the designated pH input port on your meter. Ensure a secure connection.
• Turn on the pH meter.

5. പ്രവർത്തിക്കുന്നു

This electrode is designed to work seamlessly with Oakton pH 6+ meters, utilizing their advanced features for accurate measurements.

5.1 കാലിബ്രേഷൻ

Regular calibration is crucial for accurate pH measurements. Refer to your Oakton pH 6+ meter's manual for specific calibration procedures. The WD-35811-71 electrode supports:

• Three-point pH calibration: For enhanced accuracy across a wider pH range.
• Auto buffer recognition: The meter automatically identifies standard pH buffer solutions.
• mV offset calibration: Allows for fine-tuning of the electrode's millivolt response.

5.2 അളവുകൾ എടുക്കൽ

• Rinse the electrode with distilled water before and after each measurement.
• ഇലക്ട്രോഡ് അഗ്രം s-ൽ മുക്കുക.ample ലായനി, ഗ്ലാസ് ബൾബും ജംഗ്ഷനും പൂർണ്ണമായും വെള്ളത്തിൽ മുങ്ങിയിട്ടുണ്ടെന്ന് ഉറപ്പാക്കുന്നു.
• Stir the solution gently to ensure homogeneity and allow the reading to stabilize.
• The meter's ഓട്ടോമാറ്റിക് ടെമ്പറേച്ചർ കോമ്പൻസേഷൻ (എടിസി) feature will adjust readings for temperature variations, provided a temperature sensor is connected or temperature is manually entered.
• Use the meter's പ്രവർത്തനം ഹോൾഡ് ചെയ്യുക to freeze the current reading on the display.
• The meter's യാന്ത്രിക-ഓഫ് feature will conserve battery life by automatically powering down after a period of inactivity.

6. പരിപാലനം

6.1 Cleaning the Electrode

• After each use, rinse the electrode thoroughly with distilled or deionized water.
• If the electrode becomes fouled with oil, grease, or other contaminants, clean it with a mild detergent solution or a specialized electrode cleaning solution. Follow the cleaning solution manufacturer's instructions.
• Never use abrasive materials or strong solvents to clean the electrode.

6.2 സംഭരണം

• Always store the electrode with its protective cap filled with pH electrode storage solution (e.g., 4M KCl solution).
• ഇലക്ട്രോഡ് ഒരിക്കലും ഉണങ്ങിയതോ വാറ്റിയെടുത്ത/ഡീയോണൈസ് ചെയ്ത വെള്ളത്തിലോ സൂക്ഷിക്കരുത്, കാരണം ഇത് ഗ്ലാസ് ബൾബിനെ നിർജ്ജലീകരണം ചെയ്യുകയും അതിന്റെ ആയുസ്സ് കുറയ്ക്കുകയും ചെയ്യും.
• Ensure the storage solution level covers the glass bulb and reference junction.

7. പ്രശ്‌നപരിഹാരം

• Unstable or Drifting Readings:
  • ഇലക്ട്രോഡ് ശരിയായി കണ്ടീഷൻ ചെയ്തിട്ടുണ്ടെന്നും കാലിബ്രേറ്റ് ചെയ്തിട്ടുണ്ടെന്നും ഉറപ്പാക്കുക.
  • Check for air bubbles trapped around the glass bulb.
  • Clean the electrode if it appears fouled.
  • എസ് പരിശോധിക്കുകample temperature is stable.
• മന്ദഗതിയിലുള്ള പ്രതികരണം:
  • The electrode may be dehydrated; recondition in storage solution.
  • The electrode may be dirty; clean it thoroughly.
  • The electrode may be nearing the end of its lifespan.
• No Reading or Error Message:
  • Check the connection between the electrode and the meter.
  • Ensure the meter is functioning correctly (test with another electrode if available).
  • Refer to your pH meter's manual for specific error codes.
