Detail HACH Hardness ( Total) Test Kit, Model 5-B, Drop Count Titration, 1-30 Gpg, 100 Tests: Product # : 145300

KeteranganTrust the original Hach test kit! Simple drop-count titration measures hardness as CaCO3 ( 1 gpg = 17.1 mg/ L) About water 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.
