Total Water Hardness Test Strips, 0-425 mg/L, 50 tests

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. These water hardness test strips streamline the testing process for field personnel, allowing rapid analysis of multiple samples within minutes and on-site evaluations without the need for complex setup or cleanup. Hach's water hardness test strips are trusted in laboratories worldwide for pre-test screening, effectively identifying potential interferences with lab testing protocols. Individually wrapped for maximum portability and stability, these water hardness test strips are ideal for use in various environments. Contains 50 tests.
