  • Page 4 Please examine this product carefully. Make sure that the instrument is not damaged. If any damage occurred during shipment, please contact your local Hanna Instruments Office. Each HI96721 Ion Selective Meter is supplied complete with: • Sample Cuvettes and Caps (2 pcs.) •...
  • Page 5 The validation procedure is extremely user friendly. Just use the exclusive Hanna Instruments ready‑made, NIST traceable standards to verify the performance of the instrument and recalibrate if necessary.

    Range 0.00 to 5.00 mg/L Resolution 0.01 mg/L Accuracy ±0.04 mg/L ±2% of reading @25 °C (77 °F) Light Source Tungsten lamp Light Detector Silicon Photocell with narrow band interference filter @525nm Adaptation of the USEPA method 315B and Standard Method Method 3500‑Fe B.
  • Page 7 The optical system of Hanna Instruments’ HI96 series colorimeters is based on special subminiature tungsten lamps and narrow‑band interference filters to guarantee both high performance and...
  • Page 8 A microprocessor controlled special tungsten lamp emits radiation which is first optically conditioned and beamed to the sample contained in the cuvette. The optical path is fixed by the diameter of the cuvette. Then the light is spectrally filtered to a narrow spectral bandwidth, to obtain a light beam of intensity I or I.

  • Page 10: Operating Modes

    OPERATING MODES • Measurement mode: default operation mode, enables both validation and measurement. • Calibration mode: may be entered by keeping CAL CHECK pressed for three seconds (the “CAL” tag appears), it enables calibration of the instrument. • GLP mode: may be entered by pressing GLP/ (“GLP” appears), it enables consulting of user calibration date or restore factory calibration.
  • Page 11 The instrument shows clear messages when erroneous condition appears. Messages are also displayed when the obtained values are outside expected range. The beeper is playing a beep on errors. a) on zero reading Light High: There is too much light to perform a measurement. Please check the preparation of the zero cuvette.
  • Page 12 Over Range: A flashing value of the maximum concentration indicates an over range condition. The concentration of the sample is beyond the programmed range: dilute the sample and re‑run the test. c) during calibration procedure Standard Low: The standard reading is less than expected. Standard High: The standard reading is higher than expected.
  • Page 13 The instructions listed below should be carefully followed during testing to ensure best accuracy. • Color or suspended matter in large amounts may cause interference, therefore these should be removed by treatment with active carbon and by prior filtration. • For a correct filling of the cuvette: the liquid in the cuvette forms a concavity on the top; the bottom of this concavity must be at the same level of the 10 mL mark.
  • Page 14 Prepare the instrument for measurement as follows: • Unpack the instrument by removing the dust protection sleeve from the instrument cuvette holder. • Place the battery in the instrument as described in the “BATTERY REPLACEMENT” chapter. • Place the instrument on a flat table. •...
  • Page 15 • Fill the cuvette with 10 mL of unreacted sample, up to the mark, and replace the cap. • Place the cuvette into the cuvette holder and ensure that the notch on the cap is positioned securely into the groove. •...
  • Page 16 • Remove the cuvette. • Add the content of one packet of HI93721‑0 Iron High Range reagent to the cuvette. Replace the cap and shake gently until dissolution is complete. • Replace the cuvette into the cuvette holder and ensure that the notch on the cap is positioned securely into the groove.
  • Page 17 • At the end of measurement, the instrument directly displays concentration in mg/L of iron on the LCD. INTERFERENCES Alkalinity: above 2,000 mg/L (as CaCO ). May slow down color development (negative error). To resolve this, neutralize the sample with diluted HCl Calcium (Ca ): above 10,000 mg/L as CaCO Copper (Cu...
  • Page 18 Use the validation procedure to ensure that the instrument is properly calibrated. Warning: Do not validate the instrument with any standard solutions other than the Hanna Instruments CAL Check Standards, otherwise erroneous results will be obtained. • Turn the meter on by pressing ON/OFF.
  • Page 19 • After a few seconds, the display will show “-0.0-”. The meter is now zeroed and ready for validation. • Remove the cuvette. • Place the CAL Check Standard HI96721‑11 Cuvette B into the cuvette holder and ensure that the notch on the cap is positioned securely into the groove. •...
  • Page 20 Note: It is possible to interrupt calibration procedure at any time by pressing CAL CHECK or ON/OFF keys. Warning: Do not calibrate the instrument with standard solutions other than the Hanna Instruments CAL Check Standards, otherwise erroneous results will be obtained.
  • Page 21 • After a few seconds the display will show “-0.0-”. The meter is now zeroed and ready for calibration. The blinking “READ” asks for reading calibration standard. • Remove the cuvette. • Place the CAL Check Standard HI96721‑11 Cuvette B into the cuvette holder and ensure that the notch on the cap is positioned securely into the groove.

  • Page 22: Date Input

    Then the date of the last calibration (e.g.: ”01.08.2005”) appears on the display, or “01.01.2005” if the factory calibration was selected before. In both cases the year number is blinking, ready for date input. DATE INPUT • Press GLP/ to edit the desired year (2000‑2099). If the key is kept pressed, the year number is automatically increased.
  • Page 23 • When the correct month has been set, press ZERO/CFM or READ /TIMER to confirm. Now the display will show the day blinking. • Press GLP/ to edit the desired day (01‑31). If the key is kept pressed the day number is automatically increased.

  • Page 24: Last Calibration Date

    In the GLP mode, the last user calibration date can be consulted and the factory calibration can be restored. LAST CALIBRATION DATE To display the calibration date: • Press GLP/ to enter GLP mode. The calibration month and day will appear on the main display and the year on the secondary display.
  • Page 25 • Press ZERO/CFM to restore the factory calibration or press GLP/ again to abort factory calibration restore. • The instrument briefly notifies “donE” when restores factory calibration and returns to measurement mode. To save battery, the instrument shuts down after 10 minutes of non‑use in measurement mode and after 1 hour of non‑use in calibration mode.
  • Page 26 To replace the instrument’s battery, follow the steps: • Turn the instrument off by pressing ON/OFF. • Turn the instrument upside down and remove the battery cover by turning it counterclockwise. • Extract the battery from its location and replace it with a fresh one. •...
