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 CHECK™ 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 the instrumentand recalibrate if necessary.All instruments are splash proof and the lamp and filter units are protected from dust or dirt bya transparent cup.

The cuvet is made from specialoptical glass to obtain best results.The HI 95724 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 adaption 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.GENERAL DESCRIPTIONABBREVIATIONS°C: degree CelsiusUSEPA: US Environmental Protection Agency°F: degree Fahrenheitmg/L: milligrams per liter. mg/L is equivalent to ppm (part per million)mL: milliliter21Recommendations for UsersBefore using these products, make sure that they are entirely suitable for your specific application and for the environment inwhich they are used.Operation of these instruments may cause unacceptable interferences to other electronic equipments, this requiring the operatorto take all necessary steps to correct interferences.Any variation introduced by the user to the supplied equipment may degrade the instruments' EMC performance.To avoid damages or burns, do not put the instrument in microwave oven.
