Hanna (HI93721) Waterproof Photometer - High and similar items

The iron concentration in water needs to be monitored because it becomes harmful above certain levels. In domestic water, for instance, iron can unpleasantly alter the taste, stain laundry, damage kitchenware and favor the growth of certain bacteria. Iron is also an indicator of ongoing corrosion in industrial plants or in water cooling and heating systems. Moreover, iron is normally monitored in mining wastewater to avoid contamination. Standard chemical test kits characteristically suffer from lack of precision. HANNA offers two iron meters with a clear LCD reading from 0.00 to 5.00 mg/L with a resolution of 0.01 mg/L (HI 93721) and from 0 to 400 µg\L with a resolution of 1 µg/L (HI 93746).
