About Hanna Instruments HI38033 Total Hardness 0-30 Gpg

Water hardness has traditionally been defined as the capacity of water to precipitate soap. The ionic species in the water causing the precipitation was later found to be primarily calcium and magnesium. In the present, therefore, water hardness is actually a quantitative measure of these ions in the water sample. It is also now known that certain other ion species, such as iron, zinc and manganese, contribute to the overall water hardness. The measure and subsequent control of water hardness is essential to prevent scaling and clogging in water pipes. Test kit comes with 30ml buffer solution, 10ml calmagite indicator, 75ml EDTA solution (2), 20ml plastic beaker with cap and 1ml plastic pipette. Titration method. Range: 0-30 gpg.
