The HI-708 Checker is a simple, accurate, and cost effective way to measure high ranges of nitrite
Designed as a more accurate alternative to chemical test kits, the HI 708 provides quick, accurate results in four easy steps (see below).
The HI-708 uses an adaptation of the Ferrous Sulphate method. The reaction between nitrite and the reagent causes a greenish/brown tint in the sample.
