Description
- Detects free Iodine, Chlorine, and Peroxides in a solution
- One pocket sized vial of 100 Strips
- Lower levels react with the strip at 5 to 10 ppm.
- No color chart. Turns blue/ purple in presence of sanitizer. Color darkens as concentration increases.
- Perfect for chlorine tests, iodine tests, or peroxide tests
Detects available Chlorine, Iodine, and peroxides. Turns blue/purple color, darkens as concentration increases. The Potassium Iodide Starch Paper can also work as chlorine test strips, iodine test strips, and peroxide test strips. Our 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. The Potassium Iodide Starch test paper contains potassium iodide as an active ingredient. In the presence of an oxidant, such as peroxide or chlorine, iodide is converted to iodine which then binds to starch molecules in the paper forming the blue to purple color. The color is much less intense than other more complex redox indicators. Instructions: Remove one Potassium Iodide Starch test paper from the vial, being careful not to touch the paper anywhere other than where you grasp it. Dip the paper strip into the solution to be tested for 1-2 seconds. Remove the strip and shake off any excess liquid. Chlorine and Peroxides react immediately, while Iodine requires approximately 60 seconds. Initial reactions show a slight blue color, while higher concentrations turn the strip from dark blue to purple. The upper limits for chlorine and peroxides are between 400 to 450 ppm, and the upper limits for Iodine are at 50 to 100 ppm.
