The Hach DPD-Ferrous Iron Reagent for 25 mL Samples is a high-precision powdered reagent formulated for accurate total iron (Fe²⁺ + reduced Fe³⁺) measurement in water. Supplied in single-dose, sealed powder pillows, it ensures consistent reagent strength, contamination-free handling, and repeatable results in both laboratory and field settings.
This DPD-based method reduces and complexes iron to produce a measurable color change that is easily read using compatible Hach colorimeters, photometers, and spectrophotometers. Ideal for routine iron monitoring in drinking water plants, industrial process water, boilers, cooling towers, environmental testing, and educational laboratories.
Designed for 25 mL water samples, the reagent supports a typical measuring range of 0–3.0 mg/L Fe, depending on the instrument used. Its fast reaction time and ease of use make it an essential consumable for reliable total iron testing and regulatory compliance.
Perfect For:
• Total iron testing in drinking water systems
• Industrial and process water quality monitoring
