About 4 In 1 TDS Meter ATC Function Water Quality Test
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 water purification applications, drinking water, water filtration and purification, hydroponics (testing nutrients), colloidal silver, aquarium, swimming pool and spa, etc. (TDS meter can only detect soluble solids in water, but can not detect water pollution) Tip: TDS meter has been strictly calibrated and can be used directly to avoid operating errors in the complicated calibration process water tds meter /ppm meter /EC meter / Water quality tester
