Hach Company Ferroin Indicator Solution, 29 mL DB
Oxidation-reduction indicator solution used in determination of COD by ferrous titration.
Hach Company Total Hardness Test Kit, Model HA-71A
Water hardness is caused almost entirely by calcium and magnesium ion. 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. With the Model HA-71A test kit, simply count the number of drops required to change the solution color to determine hardness concentration. Utilizing drop count titration, this kit provides dual ranges and contains approximately 100 tests.
Hach Company Chloride Test Kit, Model CD-51
Found in nearly all natural waters, chloride affects human taste above 250 mg/L. High levels inhibit plant growth, and many industrial processes need to limit chloride concentration. The model CD-DT, multi-range kit, is supplied with the demineralizer bottle for high-range sample dilution. Contains 100 tests.
