    OPERATIONAL GUIDE TAKING PH MEASUREMENTS Connect the instrument to the 12VDC adapter (HI710005 or HI710006). Plug the adapter into the mains. Make sure that the instrument has been calibrated for pH before taking pH measurements (see page 18). For HI8519 only: •...
  • Page 15 • In HI8417 the temperature reading is also displayed on the left LCD. °C Note: the electrode should be submerged approximately 4 cm (1½") into the solution. If the temperature probe is used, it should be located as close to the pH electrode as possible. If measurements are taken in different samples successively, it is recommended that the electrode is rinsed thoroughly for better condi- tioning and to eliminate cross-contamination of the sample.
  • Page 16 °C TAKING ORP MEASUREMENTS HI8417, HI8519 and HI8521 have the capability to take ORP measurements, using an ORP electrode. Hanna Instruments offers a variety of ORP electrodes for this purpose (see page 35). Contact your Dealer for more information. Just as pH measurements allow the acidity or the alkalinity of a...
  • Page 17 For HI8417 and HI8521 • Connect the ORP electrode to the meter and submerge the tip (4 cm / 1½") into the sample to be tested. Note: ORP measurements are taken without temperature compensa- tion. • Press the pH/mV key (HI8417) or RANGE RANGE key (HI8521) once to enter the mV mode.

  • Page 18: Ph Calibration

    PH CALIBRATION IMPORTANT The instrument's pH range should be re-calibrated: • When the meter is new. • Whenever the pH electrode is replaced. • At least once a month. • After use in aggressive chemicals. • After cleaning procedure and changing the reference electrolyte. •...
  • Page 19 Procedure: • Switch the instrument on after connecting the pH electrode and the temperature probe. • Immerse the pH electrode and the ATC probe into a neutral pH buffer solution (pH 7.01 for technical buffers, or pH 6.86 for NBS buffers).

  • Page 20: Procedure For Hi8519

    • The meter automatically recognizes the buffer value and prompts for the second at "d2" or "t2" (= pH 4.01, acid) or "d3" or "t3" (pH 9.18 and pH10.01 respectively, alkaline). • Press the CON key to confirm the pH value. •...

  • Page 21: Procedure For Hi8520/Hi8521

    Procedure: • Switch the instrument on after connecting the pH electrode. • Rinse and immerse the pH electrode in pH 7.01 buffer and shake briefly. Wait 1 or 2 minutes for the reading to stabilize. • Note the temperature of the buffer solution using a ChecktempC or a glass thermometer (e.g.20°C).

  • Page 22: Cal. W/ Manual Temp. Compensation

    • Press the CAL key. The temperature compensated buffer value will be displayed e.g. if the buffer temperature is at 25°C, the display will show pH7.01. If the buffer temperature is at 20°C, display will show pH 7.03 (see page 23). If "E4"...

  • Page 23: Ph Values At Various Temperature

    PH VALUES AT VARIOUS TEMPERATURE Temperature has an effect on pH. The calibration buffer solutions are effected by temperature changes to a lesser degree than normal solutions. For manual temperature calibration (standard with HI 8519 or op- tional with HI 8417, HI 8520 and HI 8521) please refer to the following chart.

  • Page 24: Troubleshooting Guide

    TROUBLESHOOTING Symptoms are: Possible Solutions: The Problem is: The instrument does Replace the probe. A defective ATC Probe not work with the HI7669/2W probe (not HI8519) The meter fails to Replace the electrode and A defective pH electrode calibrate or gives repeat the pH calibration.

  • Page 27 CLEANING PROCEDURE General Soak in Hanna HI 7061 or HI 8061 General Clean- ing Solution for approximately ½ hour. Removal of films, dirt or deposits on the membrane/junction: - Protein Soak in Hanna HI 7073 or HI 8073 Protein Cleaning Solution for 15 minutes.

  • Page 28: Temperature-Resistance Correlation

    TEMPERATURE-RESISTANCE CORRELATION The resistance of glass electrodes partially depends on the tempera- ture. 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 tempera- tures below 10°C.
  • Page 29 High concentrations of sodium ions interfere with readings in alkaline solutions; the pH at which the interference starts to be significant depends upon the composition of the glass. This interference is the alkaline error and causes the pH to be underestimated. Hanna's glass formulations have the indicated characteristics.
