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.
Detects:
0, 2, 5, 10, 20, 40, 100 ppm (mg/L)
