• Complete K-6901 nitrate testing platform with both low-range and high-range comparators included.
• Measures nitrate from 0–0.1 ppm and 0–1.4 ppm (as N) directly, with expanded measurement capability available through dilution procedures.
• Minimum Detectable Level (MDL): 0.01 ppm (as N) for LR; 0.1 ppm (as N) for HR.
• Ideal for drinking water, private wells, groundwater, source water, environmental monitoring, and laboratory applications.
• Utilizes the Zinc Reduction – Azo Dye Formation (NED) method, eliminating cadmium-based waste while providing excellent sensitivity and resolution.
• Complete kit includes a Nitrate Refill package (30 ampoules, zinc granules, acidifier solution, and buffer solution), low-range comparator, high-range comparator, reaction tube with lid, sample handling accessories, 25 mL sample cup, and instructions.
• Provides up to 30 nitrate tests.
• Supports multiple optional dilution procedures for measuring concentrations beyond the standard low-range scale.
• Durable plastic case for convenient storage and portability.
• Cross-compatible reagents: R-7006 ampoules and S-7004 acidifier solution from this kit can also be used with K-7006, K-7030B, and K-7030C Nitrite CHEMets® Test Kits, and vice versa.
