Hanna Instruments HI96718C Cal Check Iodine Portable Photometer Kit with Case

The disinfectant properties of iodine have led to its use as an alternative to chlorine and bromine. Unlike chlorinated pools, water treated with iodine decreases eye irritation among swimmers, and provides a level of disinfection more stable to adverse conditions. However, its toxic and corrosive properties and the difficulties of dissolving it in water has limited it’s widespread acceptance. One of its most common applications is in poultry industry process water. The cuvette is made from special optical glass to obtain best results. The HI 96718 measures the iodine content in water samples in the 0.0 to 12.5 milligrams per liter (ppm) range.
