Hanna HI746-25 – Reagent Set for Iron Low Range Checker HC (25 Tests)
The Hanna HI746-25 Iron Low Range Reagnet includes 25 pre-measured packets formulated for use with the Hanna HI746 Iron Low Range Checker HC. These reagents allow users to quickly and accurately measure iron concentrations in water from 0 to 999 ppb, using the trusted TPTZ colorimetric method.
Because the reagents are conveniently packaged in single-use sachets, testing becomes faster, more consistent, and free from the errors associated with manual measurements.
Key Features
High Accuracy Testing
Designed to match the sensitivity of the HI746 Checker HC, these reagents support readings down to 1 ppb, with an accuracy of ±20 ppb ±5% at 25°C. This makes them ideal for ultra-low iron monitoring.TPTZ Method Compliance
These reagents follow the TPTZ (2,4,6-Tri(2-pyridyl)-s-triazine) Method, where iron reacts with the chemical reagent to form a violet-colored complex. The device then interprets this color intensity to determine the iron concentration in parts per billion (ppb).Ready-to-Use Convenience
Each reagent sachet contains the exact amount needed for one test—just tear open, pour into the sample, and proceed. This saves time while ensuring consistency between tests.Made for Low Range Applications
Optimized for samples in the 0 to 999 ppb range, this reagent set is ideal for sensitive water quality monitoring in both field and lab environments.
