WaterWorks™ Zinc Check
WaterWorks™ Zinc Check for water quality testing is designed for detection of Zinc in water. There are no hazardous chemicals to mix and MSDS is not required. Note: Similar positive color development shows up with the presence of Cu+2 (>0.1mg/L), Mn+2 (>5 mg/L), and Fe+2 (>10 mg/L). Most interference from other metals can be overcome by adjusting the pH between 4.0 to 5.5 and adding sufficient Sodium Thiosulfate before test analysis.
Contains 50 tests.
0, 2, 5, 10, 20, 40, 100 ppm (mg/L)
