Hanna Instruments HI-38040 Iron checker Disc, (Fe2+ & Fe3+) medium range
Colorimetric testing is a method of determining the concentration of a chemical element or compound (organic or inorganic) in a solution with the aid of a colour reagent.
Using Hanna special reagents, our test kits measure the strength or weakness of a chemical presence according to the degree of colour saturation. Ie – if it is pale in colour, then the chemical concentration is low. If the colour is strong, then the chemical concentration is high. Simply add the reagent to the compound to be tested and match the colour gained against a colour chart included in the kit.
Iron MR, Checker disc; phenanthroline colorimetric chemical method.

Significance of Use
Iron is naturally present in water in low concentrations, but it reaches high concentrations in wastewater effluents.
The iron concentration in water needs to be monitored because it becomes harmful above certain levels.
In domestic water for instance, iron can stain laundry, damage kitchenware, favour the growth of certain bacteria, and unpleasantly alter the taste of water. Iron is also an indicator of ongoing corrosion in water cooling and heating systems. Moreover, iron is normally monitored in mining wastewater to avoid contamination.
