Potassium Iodide Starch Paper vial of 100strips

The Potassium Iodide Starch test paper detects free Iodine, Chlorine and Peroxides in solution. Lower levels react with the strip at 5 – 10 ppm. Iodine requires approximately 60 seconds to react, and initial reactions show a slight blue color, while higher concentrations turn the strip from dark blue to purple. Our Potassium Iodide Starch Paper is also available in a military grade (See Additional Information).
