iCheck Iodine

iCheck Iodine measures iodine in salt

iCheck™ Iodine is a state-of-the–art and the first of its kind portable photometer. It determines iodine quantitatively. iCheck™ Iodine measures the purple color reaction in the test vial and calculates the iodine content in mg/L. It is used to measure iodization level in salt.
