Full Description Specification Manuals

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 concentration in natural water is typically below 1 mg/L (ppm), but the level can be much higher due to industrial discharges. Water containing iron is not dangerous to health, but it has a strong taste and can stain.

Hanna test kits allows you to determine the total concentration of iron as both Fe²+ and Fe³+ ionic status.
