Hanna HI746-25 Iron Low Range Reagnet

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.
