The HI719 Checker®HC is a simple, accurate, and cost effective way to measure magnesium hardness. The HI720 Checker®HC is a simple, accurate, and cost effective way to measure calcium hardness.
The HI719 uses an adaptation of the Standard Methods for the Examination of Water and Wastewater, 18th edition, EDTA colorimetric method. The reaction between magnesium and reagents causes a reddish-violet tint in the sample.
The HI720 uses an adaptation of the Standard Methods for the Examination of Water and Wastewater, 18th edition, Calmagite method. The reaction between calcium and reagents causes a reddish-violet tint in the sample.
