All for health: Global water quality issues are frequent and affect our health. We need to quickly identify and ensure that household drinking water is safe and clean, free from common contaminants and not exceeding EPA's recommended contaminant levels (Maximum Contaminant Levels). Save money/test 100 times: Drinking water test kit supports 16 parameters per test strip, totaling 100 strips, equivalent to 2000 water tests with one product. This would save you from lab tests of these separately at a cost of thousands of dollars and long waiting times. You can stay updated on your water quality. 16-in-1 home water test kit: Drinking water test kit includes 16 parameters, covering all the main contaminants you need to worry about, and can test total hardness, free chlorine, total chlorine, bromine, total alkalinity, pH, nitrate, nitrite, copper, iron, lead, nickel, carbonate, MPS, cyanuric acid, and sulfite. It can detect problems in drinking water. If you have any issues with our products, please contact us.
