  • Page 7: Required Reagents

    Method For pH: Phenol red method. The reaction with the reagent causes a red tint in the sample. For Chlorine: Adaptation of the EPA, DPD method and Standard Method 4500‑Cl G. The reaction between chlorine and the reagent causes a pink tint in the sample.
  • Page 8 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 9 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 10 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 13 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 14 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 15 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;...
  • Page 16 • It is important that the sample does not contain any debris. This would corrupt the reading. • Each time the cuvette is used, the cap must be tightened to the same degree. • Whenever the cuvette is placed into the measurement cell, it must be dry outside, and completely free of fingerprints, oil or dirt.
  • Page 17 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 18 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. Important note: Free and Total Chlorine have to be measured separately with fresh unreacted samples if both values are requested.

    Interferences Interference may be caused by: Bromine, Iodine, Chlorine Dioxide, Ozone, Oxidized Manganese and Chromium. In case of water with alkalinity greater than 250 mg/L CaCO or acidity greater than 150 mg/L CaCO the color of the sample could disappear or develop only partially. To resolve this, neutralize the sample with diluted HCl or NaOH.
