Tungsten lamp Silicon Photocell with narrow band interference filter @ 525 nm For pH: Phenol red method. The reaction with reagents causes a red tint in the sample. For Chlorine: Adaptation of the USEPA method and Standard Method 4500-Cl G. The reaction with reagents causes a pink tint in the sample. For Cyanuric Acid: Adaptation of the turbidimetric method. The reaction between cyanuric acid and the reagent causes a white suspension in the sample. For Iodine: Adaptation of the EPA, DPD method.
PRECISION AND ACCURACY 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.
PRINCIPLE OF OPERATION Absorption of Light is a typical phenomenon of interaction between electromagnetic radiation and matter. When a light beam crosses a substance, some of the radiation may be absorbed by atoms, molecules or crystal lattices.
The photoelectric cell collects the radiation I that is not absorbed by the sample and converts it into an electric current, producing a potential in the mV range. The microprocessor uses this potential to convert the incoming value into the desired measuring unit and to display it on the LCD. The measurement process is carried out in two phases: first the meter is zeroed and then the actual measurement is performed.

ERRORS AND WARNINGS 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. Light Low: There is not enough light to perform a measurement. Please check the preparation of the zero cuvette. No Light: The instrument cannot adjust the light level.
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. d) other errors and warnings Cap error: Appears when external light enters in the analysis cell. Assure that the cuvette cap is present.
GENERAL TIPS FOR AN ACCURATE MEASUREMENT 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.
• 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. Wipe it thoroughly with HI 731318 or a lint-free cloth prior to insertion. • Shaking the cuvette can generate bubbles in the sample, causing higher readings.
RANGE SELECTION The HI 96101 can measure pH when range P1 is selected, Free Chlorine when range P2 is selected, Total Chlorine when range P3, Cyanuric Acid when range P4, Iodine when range P5, Bromine when range P6, Iron LR when range P7 are selected. To change the active range follow the procedure: • Turn the meter on by pressing ON/OFF. The display briefly shows all tags on. • After startup, the range identification number is displayed on the secondary LCD as P1, P2, P3, P4, P5, P6 or P7.
• When the beeper sounds briefly and the LCD displays dashes, the meter is ready. The blinking “ZERO” indicates that the instrument needs to be zeroed first. Note: Pay attention that the selected range is the one desired to run measurements. If not, change the range following the instructions from Range Selection. pH MEASUREMENT • Fill the cuvette with 10 mL of unreacted sample, up to the mark, and replace the cap.
