Test Strip; Water Hardness; 0 to 120ppm Hardness
Serim GUARDIAN Water Hardness Test Strips give a semi-quantitative indication of the level of hardness in water. Hardness is used to describe the total concentration of calcium and magnesium ions, expressed as ppm (or grains per gallon) of calcium carbonate, CaCO3.
