4GENERAL DESCRIPTIONABBREVIATIONSThe HI 96724 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 tungsten lamp and a narrow band interference filter that allows mostaccurate and repeatable readings. All instruments are factory calibrated and the electronic andoptical 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 lamp 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 in measurement mode or after 1 hour if left incalibration mode.The meter uses an exclusive positive-locking system to ensure that the cuvet is in the sameposition every time it is placed into the measurement cell. It is designed to fit a cuvet with alarger neck making it easier to add both sample and reagents. The cuvet is made from specialoptical glass to obtain best results.The HI 96724 meter measures the free and total chlorine (Cl2) content in water samples in the0.00 to 5.00 mg/L (ppm) range. The method is an adaptation of the USEPA Method 330.5 forwastewater, and Standard Method 4500-Cl G for drinking water.The reagents are in liquid form and are supplied in dropper bottles. The amount of reagent isprecisely dosed to ensure the maximum repeatability.degree CelsiusUS Environmental Protection Agencydegree Fahrenheitmilligrams per liter. mg/L is equivalent to ppm (part per million)millilitermillivolts°C:EPA:°F:mg/L:mL:mV:
