Hach Total Hardness Test Strips, 0-425 mg/L, 2745250

Description

Water hardness is caused almost entirely by calcium and magnesium ions. Other di- and trivalent metals have a similar effect, but usually are not present in high enough concentration in potable waters to cause problems. Hardness increases soap consumption in laundries and causes scale in boilers. Contains 50 tests.
