Ppm is the unit of hardness of water. Hardness refers to the concentration of calcium and magnesium ions in water. 1 ppm represents the content of calcium carbonate in water of 1 mg/L. When the concentration of Ca and Mg in water is lower than 80 ppm, it belongs to soft water. The higher the PPM value, the higher the hardness of water, the longer the drinking water will be, which will lead to calcium precipitation in the body and cause stones and other symptoms TDS meter is suitable for all wate
