Water hardness, also known as groundwater hardness, refers to the content of Ca2+ and Mg2+ ions in water (no longer used in standard terminology). Refers to the total concentration of calcium and magnesium ions in water, including carbonate hardness (that is, calcium and magnesium ions that can be precipitated in the form of carbonate by heating, so it is also called temporary hardness) and non-carbonate hardness (that is, the part of calcium and magnesium ions that cannot be precipitated after heating, also known as permanent hardness). Why do you know the importance of monitoring water hardness after you understand it? This chapter water quality online monitoring instrument manufacturers to understand the water hardness and monitoring together!

Water hardness is an important indicator of water quality, which is closely related to industrial water use. It is the main factor to form pot scale and affect product quality. Therefore, the total hardness of water, that is, the determination of the total amount of calcium and magnesium in water, provides a basis for determining the quality of water and water treatment.

Water hardness testing and analysis is an important work in water quality analysis, which affects public production and life safety. In the early stage, most of the determination methods are laboratory determination, and on-site online analysis is less. At the same time, analysis methods for determining multiple elements are not widely used. However, with the development of modern chemistry, more and more began to use water quality online monitoring equipment, which convenient for later staff to save a lot of time, of course, still need to be further improved.

T8000-WH water hardness online analyzer is a new generation of automatic online analyzer developed technically based on China’s standard method. This product is a maintenance-free instrument launched by Moody Technology on the basis of years of research on water quality analysis products. Suitable for water softening monitoring, reverse osmosis system, filtration and mineral removal process control, widely used in pharmaceutical, steel, semiconductor industries. The pre-treated water sample is injected into a special reactor by an injection pump for pre-treatment of the water sample. After the reaction, the water sample is detected by highly selective synthetic substances and special sensors, which have a linear relationship with the hardness of the water signal. According to the degree of electrical change, the hardness of the water sample can be calculated.
