Hanna HI3812 Total Hardness Test Kit

Hanna HI3812 Total Hardness Test Kit, Water hardness has traditionally been defined as the capacity of water to subside soap. The ionic species in the water causing the precipitation was later found the chemicals 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 are essential to prevent scaling and clogging in water pipes.
