HI 96771 has been developed to check chlorine dosing in disinfection processes with ultra high concentrations of chlorine. Thanks to the extended range from 0 to 500 mg/L (ppm), it is ideal for the food industry, such as in fruit and vegetable washing.
The HI 96771 meter measures the free chlorine (Cl2) 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. It is designed to fit a cuvette with a larger neck making it easier to add both sample and reagents. The cuvette is made from special optical glass to obtain best results.
HI 96771 is supplied with sample cuvettes with caps (2), 9V battery and instruction manual.
HI 96771C includes HI 96771 photometer, sample cuvettes with caps (2 ea.), CAL CHECK standard cuvettes (2), 9V battery, scissors, cloth for wiping cuvettes, instrument quality certificate, instruction manual and rigid carrying case.
