4 5GENERAL DESCRIPTIONABBREVIATIONSSPECIFICATIONSPRECISION AND ACCURACYThe HI 96753 is an auto diagnostic portable microprocessor meter that benefits from Hanna’syears of experience as a manufacturer of analytical instruments. It has the advanced opticalsystem based on a special Light Emitting Diode (LED) and a narrow band interference filter thatallows most accurate and repeatable readings. All instruments are factory calibrated and theelectronic and optical design minimizes the need of frequent calibration.With the powerful CAL CHECKTM validation function, you are able to validate good performanceof your instrument at any time. The validation procedure is extremely user friendly. Just use theexclusive HANNA ready-made, NIST traceable standards to verify the performance of theinstrument and recalibrate if necessary.All instruments are splash waterproof and the LED and filter units are protected from dust or dirtby a transparent cup. This makes the instruments fulfill field applications. Display messages aidthe user in routine operation. The meter has an auto-shut off feature that will turn off theinstrument after 10 minutes of non use inmeasurement mode or after 1 hour if left incalibration mode.The meter uses an exclusive positive-locking system to ensure that the cuvette is in the sameposition every time it is placed into the measurement cell. It is designed to fit a cuvette with alarger neck making it easier to add both sample and reagents. The cuvette is made from specialoptical glass to obtain best results.The HI 96753 meter measures the chloride (Cl–) content in water and wastewater samples inthe 0.0 to 20.0 mg/L (ppm) range. The method is an adaptation of the mercury(II) thiocyanatemethod.The reagents are in liquid form and are supplied in bottles. The amount of reagent is preciselydosed to ensure the maximum repeatability.degree Celsiusdegree Fahrenheitmilligrams per liter. mg/L is equivalent to ppm (parts per million)millilitermillivolts°C:°F:mg/L:mL:mV:Range 0.0 to 20.0 mg/LResolution 0.1 mg/LAccuracy ±0.5 mg/L ±6% of reading @ 25°CTypical EMC Deviation ±0.1 mg/LLight Source Light Emitting DiodeLight Detector Silicon Photocell with narrow band interference filter @ 466nmMethod Adaptation of the mercury(II) thiocyanate method.

Precision is usuallyexpressed as standard deviation (SD).AccuracyAccuracyAccuracyAccuracyAccuracy is defined as the nearness of a testresult to the true value.Although good precision suggests good accuracy,precise results can be inaccurate. The figureexplains these definitions.In a laboratory using a standard solution of10.0 mg/L chloride and a representative lot ofreagent, an operator obtained with a singleinstrument a standard deviation of 0.3 mg/L.
