Hanna Nitrate Low Range Reagents – 25 Tests (HI781-25)

The HI781-25 reagents are high-quality replacement reagents for the HI781 Marine Nitrate Low Range Checker HC. Each packet is pre-measured, allowing for fast, accurate, and consistent nitrate measurements every time.

Easy-to-Use Pre-Measured Reagents

The HI781-25 reagents come pre-measured, simplifying the testing process for both hobbyists and professionals. Users can achieve reliable results without the need for additional preparation.

Colorimetric Method for Accuracy

These reagents use a colorimetric method, where the reaction between nitrate and the reagent produces a pink/violet tint in the sample. The HI781 then determines the nitrate concentration in ppm, providing precise readings for reef aquariums and marine systems.
