About Hanna Instruments HI3812 Single Parameter Hardness
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. The HI 3812 test kit tests the hardness level as milligram per liter (ppm) calcium carbonate, via an EDTA (ethylene-diamine-tetraacetic acid) titration. The HI 3812 test kit tests the hardness level as milligram per liter (ppm) calcium carbonate is determined by an EDTA (ethylene-diamine-tetraacetic acid) titration. HI 3812 test kit comes with 30mL hardness buffer, 10mL calmagite indicator, 120mL EDTA solution, 20mL plastic beaker with cap, 50mL plastic beaker with cap and 1mL syringe with tip.
