  • Page 7 Note: To prevent damage to the electrode, remove the pH elec- trode from the solution before turning the meter off. If the meter is OFF, detach the electrode from the meter before immersing the electrode in the storage solution. TAKING pH MEASUREMENTS Make sure that the instrument has been calibrated for pH before taking pH measurements.

  • Page 8: Ph Calibration

    TAKING ORP MEASUREMENTS HI2209 and HI22091 have the capability to take ORP measurements, using an ORP electrode. Hanna Instruments offers a variety of ORP electrodes for this purpose (see accessories). Contact your local Hanna Instruments Office for more information. • Connect the ORP electrode to the meter and submerge the tip (4 cm / 1½") into the sample...
  • Page 9 If you are measuring in the acid range, use pH4.01 as second buffer; if you are measuring in the alkaline range, use pH10.01 as second buffer. For accurate calibration, use two beakers for each buffer solution; the first for rinsing the electrode, the second for calibration. In this way, contamination of the buffer is minimized.
  • Page 10 • Wait a couple of minutes and adjust the Offset knob until display shows the pH value at the noted temperature (see the pH versus temperature chart). • Rinse and immerse the pH electrode in pH4.01 / pH10.01 buffer and shake briefly. •...

  • Page 11: Ph Buffer Temperature Dependence

    pH BUFFER TEMPERATURE DEPENDENCE Temperature has an effect on pH. The calibration buffer solutions are affected by temperature changes to a lesser degree than normal solutions. For manual temperature calibration please refer to the following chart. TEMP pH BUFFERS °C °F 4.01 6.86...

  • Page 12: Electrode Conditioning And Maintenance

    ELECTRODE CONDITIONING AND MAINTENANCE Note: To prevent damage to the electrode, remove the pH elec- trode from the solution before turning the meter off. If the meter is OFF, detach the electrode from the meter before immersing the electrode in the storage solution. PREPARATION PROCEDURE Remove the protective cap.
  • Page 13 For refillable electrodes: If the fill solution (electrolyte) is more than 2½ cm (1") below the fill hole, add HI7082 3.5M KCl electrolyte solution for double junction or HI7071 3.5M KCl+AgCl electrolyte solution for single junction electrodes. For a faster response, unscrew the fill hole screw during measurements.
  • Page 14 1 hour. • Drifting: soak the electrode tip in warm (approx. 50-60 °C) Hanna Instruments HI7082 solution for one hour and rinse the tip with distilled water. Refill with fresh HI7071 for single junction electrodes and HI7082 for double junction electrodes (refillable electrodes only).
  • Page 15 TEMPERATURE CORRELATION FOR pH SENSITIVE GLASS The resistance of glass electrodes partially depends on the temperature. The lower the temperature, the higher the resistance. It takes longer time for the reading to stabilize if the resistance is higher. In addition, the response time will suffer to a greater degree at temperatures below 10 °C.
