iCheck Iron
iCheck™ Iron is a state-of-the–art device. This first of its kind portable photometer determines iron quantitatively. iCheck™ Iron measures the color reaction in the reagent vial and calculates the iron content in mg Fe/L. It is used to measure Iron in vitamin premixes, flour, soy- and fish-sauce and beverages.
