The HI721-25 reagents are suitable for measuring iron in the high range from 0.00 to 5.00 mg/L with the HI721 Checker photometer for Iron HR. The reagents are used for the photometric determination of iron in natural and treated waters according to an adaptation of the EPA phenanthroline method 315B. During the analysis, iron in the water sample reacts with the reagent, after which the HI721 measures the resulting colour reaction and determines the iron concentration. One pack contains powder reagents for 25 Iron HR measurements and is suitable as a refill or replacement for the reagents supplied with the HI721 Checker photometer starter kit.
