Hardness - 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.
Fast, reliable and safe test strips from Hach: - Hach Test Strips are easy to use and easy to read. In the field, technicians can test many samples in only a few minutes, and make immediate evaluations on-site. In the lab, Hach test strips are ideal in pre-test screening to detect the presence of materials that might interfere with lab testing.
