Hanna Instruments HI96771 Ultra High Range Free Chlorine Portable Photometer with Sample Cuvettes, 7-19/32" Length x 4-3/32" Width x 2-11/16" Height, 0 - 500 mg/L UHR, 9V Battery

HI96771 has been developed to check chlorine dosing in disinfection processes with ultra high concentrations of chlorine. The extended range from 0 to 500 milligrams per liter (ppm), it is ideal for the food industry, such as in fruit and vegetable washing. The HI96771 meter measures the free chlorine content in water samples and chlorine ultra high range. The methods are an adaptation of standard methods for the examination of water and wastewater, 20th edition, 4500-Cl. The meter uses an exclusive positive-locking system to ensure that the cuvette is in the same position every time it is placed into the measurement cell.
