Boiler water softening water hardness tester

What is softened water? Why monitor the hardness of water quality?

Water can be classified into soft and hard types, with the main criterion being its hardness, which refers to the concentration of calcium and magnesium ions in the water. Softened water refers to the process of dissolving water into water

Hardness (mainly referring to the removal or reduction of calcium and magnesium ions in water) to a certain extent. During the softening process of water, only the hardness decreases, while the total content

The salt content remains unchanged.

The detection and analysis of water hardness is an important task in water quality analysis, which affects public production and life safety. It is an indicator of water quality

Important indicators.The hardness of water is the main factor that forms scale and affects product quality. Therefore, monitoring the total hardness of water refers to the total amount of calcium and magnesium in the water

The determination,It can provide a basis for determining water quality and conducting water treatment.
