Quick and easy way to determine water hardness levels in lab or in the field.
Ready-to-use Test Strips (p/n 2745250) are required for determination of total hardness 0-425 mg/L in the laboratory or in the field. Water hardness is caused by calcium and magnesium ions. Total Hardness Test Strips may be used to analyze 40 samples. The smallest increments steps are 0, 25, 50, 120, 250 and 425 ppm.
