Hach 145300 Total Hardness Test Kit, Model 5-B


Water hardness is caused almost entirely by calcium and magnesium ions
Hardness increases soap consumption
Hardness test kits include the inexpensive Models 5-B and 5-EP

Water hardness is caused almost entirely by calcium and magnesium ions. Other di- and trizalent 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. Hardness test kits include the inexpensive Models 5-B and 5-EP designed for those needing quick checks on the efficiency of water softeners. More sophisticated test kits allow the determination of total hardness as well as calcium and magnesium (by difference).

Does this come with all required test tubes, etc needed to do tests?
Answer: Yes, test kit includes tube to accurately measure sample size and bottle to perform test.
Also included is a plastic measuring scoop for the dry indicator to be added to the sample. Testing is simple and works well.
