- 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 HI96739 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.
- Page 6 Range 0.0 to 20.0 mg/L Resolution 0.1 mg/L Accuracy ±0.5 mg/L ±3% of reading @25 °C (77 °F) Light Source Tungsten lamp Light Detector Silicon Photocell with narrow band interference filter @575nm Adaptation of the EPA method 340.1 and Standard Method for the Examination of Water and Wastewater, 20 edition, SPADNS method.
- Page 7 Precision is how closely repeated measurements agree with each other. Precision is usually expressed as standard deviation (SD). Accuracy is defined as the nearness of a test result to the true value. Although good precision suggests good accuracy, precise results can be inaccurate. The figure explains these definitions.
- Page 8 The optical system of Hanna Instruments’ HI96 series colorimeters is based on a special subminiature tungsten lamp and narrow‑band interference filters to guarantee both high performance and...

- Page 10 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. • For adding the exact amount of sample and reagent to the cuvette it is recommended to use three class A laboratory pipettes. class A pipette •...
- Page 14 • In order to avoid reagent leaking and to obtain more accurate measurements, it is recommended to close the cuvette first with the supplied HPDE plastic stopper and then with the black cap. • Whenever the cuvette is placed into the measurement cell, it must be dry outside, and completely free of fingerprints, oil or dirt.
- Page 15 To compensate the meter for the sample turbidity or color, the measurement takes place in two phases. First, the meter is zeroed using the unreacted sample. After the reagents are added the reacted sample is measured. • Turn the meter on by pressing ON/OFF. The display briefly shows all tags on. •...
- Page 16 • Place the cuvette into the cuvette holder and ensure that the notch on the cap is positioned securely into the groove. • Press ZERO/CFM and the lamp, cuvette and detector icons will appear on the display, depending on the measurement phase. •...
- Page 17 • Replace the cuvette into the holder and ensure that the notch on the cap is positioned securely into the groove. • Press READ and the lamp, cuvette and detector icons will appear on the display, depending on the measurement phase. •...
- 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. For accurate validation, please perform test at room temperature: 18 to 25 °C (64.5 to 77.0 °F) •...
- 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 HI96739‑11 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. For accurate validation, please perform test at room temperature: 18 to 25 °C (64.5 to 77.0 °F)
- 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 HI96739‑11 Cuvette B into the cuvette holder and ensure that the notch on the cap is positioned securely into the groove.
- Page 22 Then the date of the last calibration (e.g.: ”01.08.2009”) appears on the display, or “01.01.2009” 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 (2009‑2099). If the key is kept pressed, the year number is automatically increased.
- Page 23 • Press GLP/ to edit the desired day (01‑31). If the key is kept pressed the day number is automatically increased. Note: It is possible to change the editing from day to year and to month by pressing READ. • Press ZERO/CFM to save the calibration date. •...
- Page 24 In GLP mode, the last calibration date can be verified 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” upon restoration of factory calibration prior to returning to measurement mode. BATTERY MANAGEMENT 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. •...
