Why Test Manganese Levels?Manganese testing is critical for drinking water quality and regulatory compliance. In drinking water, manganese causes metallic taste, black staining of fixtures and laundry, and can pose health concerns at elevated levels. The EPA secondary standard is 0.05 mg/L, while the health advisory level is 0.3 mg/L for infants and 1.0 mg/L for adults. In industrial water, manganese can cause scaling, corrosion, and biological fouling. The HI709's high range (0-20 mg/L) is specifically designed for well water, groundwater, and industrial applications where manganese levels can be significantly elevated.How to Use:
Fill cuvette with 10 mL water sample to line
Add HI709 reagent packet and mix thoroughly
Wait for color development (3 minutes)
Insert cuvette into HI709 Checker HC
Press button to read manganese concentration in mg/L
Reagent Availability:Replacement reagents available separately as HI709-25 (25 tests) and HI709-100 (100 tests). Each reagent packet is pre-measured for consistent, accurate results.Maintenance & Care:Clean cuvettes with distilled water after each use. Store in protective case when not in use. Replace battery when low battery indicator appears. Use CAL Check feature periodically to verify meter performance. Keep reagents stored in a cool, dry place.Note: Reagents sold separately after initial supply is used. For best results, use fresh reagents and follow all testing procedures carefully. Regular CAL Check validation recommended for quality assurance.
