HANNA Total Hardness

HANNA Total Hardness is a chemical test kit that asseses the overall hardness concentration through advanced features such as pre-made reagents and equipment that maximizes the analysis. Water hardness is produced from elevated levels of magnesium and calcium from the water, and is the primary cause of scaling and clogging occurring in industrial and commercial establishments. As a result, water treatment plants utilize these test kits to prevent water quality issues.
