HI 38079
Magnesium Test Kit for Irrigation Water

Product Description:
By using the HI 38079 HANNA test kit, it is possible to differentiate between calcium and magnesium, since the kit determines only the magnesium ions.

The HANNA test kit determines magnesium in irrigation water via a titrimetric method. Calcium, if present, is removed by prior filtration. Then the indicator chelates with magnesium to form a red colored complex; as EDTA is added, magnesium complexes with it: the reaction endpoint is indicated by a change in color of the indicator from red to blue.
