Hanna Instruments HI1285-6 pH/EC/TDS multiparameterprobe brugermanual

1. Introduktion

The Hanna Instruments HI1285-6 is a multiparameter probe designed for simultaneous measurement of pH, Electrical Conductivity (EC), and Total Dissolved Solids (TDS). This probe is specifically engineered as a replacement for the GroChek HI9813 meter, ensuring accurate and reliable readings for various applications, including hydroponics, agriculture, and environmental monitoring. This manual provides essential information for the proper setup, operation, and maintenance of your HI1285-6 probe.

2. Opsætning og installation

Proper setup is crucial for accurate measurements. Follow these steps to install your HI1285-6 probe:

1. Udpakning: Carefully remove the probe from its packaging. Inspect for any visible damage.
2. Konnektor: Ensure the probe's connector is clean and dry. Align the connector with the corresponding port on your compatible meter (e.g., GroChek HI9813).
3. Sikker forbindelse: Gently push and twist the connector until it is firmly seated. Avoid overtightening.
4. Pre-conditioning: Before first use, or after prolonged storage, immerse the probe tip in HI70300 storage solution for at least 30 minutes to hydrate the pH glass bulb.
5. Skylning: Rinse the probe tip with deionized water before and after each measurement.

3. Betjeningsvejledning

The HI1285-6 probe is designed for use with compatible Hanna Instruments meters. Refer to your meter's instruction manual for specific operational procedures. General guidelines are provided below:

• Kalibrering: Regular calibration is essential for accurate readings. Calibrate the pH, EC, and TDS functions according to your meter's instructions using fresh calibration solutions. The CAL Check feature, if supported by your meter, assists in verifying probe condition.
• Måling:
  1. Dyp probespidsen ned i sample solution, ensuring the sensing elements are fully submerged.
  2. Gently stir the probe to remove any air bubbles and allow the reading to stabilize.
  3. Record the stabilized readings from your meter.
• Temperaturkompensation: The probe features built-in temperature compensation for accurate EC/TDS readings. Ensure your meter is set to the correct temperature compensation mode.

4. Vedligeholdelse og opbevaring

Proper maintenance extends the life and accuracy of your probe:

• Rensning:
  • After each use, rinse the probe thoroughly with deionized water.
  • If deposits are visible, clean the probe with a suitable cleaning solution (e.g., Hanna Instruments HI7061 for general purpose).
  • Never scratch or rub the glass bulb or platinum sensors.
• Opbevaring:
  • Always store the pH/EC/TDS probe with its tip immersed in HI70300 storage solution. Never store in deionized water.
  • Ensure the protective cap is filled with storage solution and securely placed over the probe tip when not in use.
• Elektrolytniveau: For refillable probes (if applicable to your specific HI1285-6 variant), ensure the electrolyte level is maintained above the reference junction.
