1、 Product Usage:

Water hardness refers to the total concentration of calcium and magnesium ions in a water sample, and it is an important indicator of water quality. The YD200A water hardness tester uses electrode method for testing, and extensive experiments have shown that it has the same accuracy as EDTA titration method. It is suitable for detecting water hardness concentration in large, medium, and small water plants, industrial and mining enterprises, domestic or industrial water, in order to control water hardness to meet the specified water quality standards.
