Description
Hach 5B Water Hardness Test Kit
The Hach 5B Kit is an economical analyzer for measuring hardness in water.
It uses a drip reagent that shows the hardness as CaCO3 (1 gpg = 17.1 mg/L).
Kit Hach 5B gives us a parameter of 1-30 gpg. (parts per gallon).
Water hardness is due to the amount of calcium and magnesium present in the water. In addition, there are other minerals that can generate incrustation, but they are usually found in very low concentrations.
The hardness in the water when these salts and minerals precipitate, generates incrustations in: metallic piping, industrial machinery, household appliances, coffee machines, washing equipment, boilers, water heaters, etc.

About water hardness: Water hardness is almost entirely due to calcium and magnesium ions. Other di- and trivalent metals have a similar effect, but are generally not present in high enough concentrations in drinking water to cause problems. Hardness increased soap consumption in laundries and increased scale in boilers and pipes.
Instructions for use of the Hach 5B Kit
1. Fill the test tube (Cat. No. 438-00) to the rim with the sample.
2. Pour sample into a mixing bottle (Cat. No. 49-06).
3. Add one level tablespoon (Cat. No. 511-00) of UniVer 3 Hardness Reagent (Cat. No. 231-20).
4. Add Hardness 3 Titrating Solution (Cat. No. 426-32) to the mixing bottle, drop by drop, while stirring circularly. When the color of the sample changes from pink to blue, note the number of drops that have been added.
Note: If blue color appears with a single drop of titrant, then the total hardness is < 1 grain per gallon.
5. Number of drops = Total hardness of the sample in grains (grains) per gallon as CaCO3.
