HI721-25 are replacement reagents for Checker® HC for Iron. These high-quality reagents are manufactured in our state-of-the-art facilities and are clearly marked for traceability with the lot number and expiration date on each packet.
The HI721-25 reagents are high-quality pre-dosed reagents that allow users to obtain quick and accurate measurements with their Checker® HC for Iron. The reagents follow the phenanthroline method where the reaction between the iron and the reagents causes an orange color in the sample.
By simply adding a packet of HI721-25 reagent to the sample, the reaction will occur and the HI721 will be able to determine the concentration from the resulting color. The results will be displayed in ppm (mg/L) of iron. These reagents are designed to be used with samples having an expected range of 0.00 to 5.00 ppm of iron.
