Facilities, Cleaning & PestsQuestion 291 of 320
For an iodine-based (iodophor) sanitizer, which concentration range is generally correct?
a.50 to 100 ppm
b.200 ppm minimum
c.12.5 to 25 ppm
d.500 ppm or higher
Explanation
Iodine sanitizers, or iodophors, are effective at roughly 12.5 to 25 ppm within the manufacturer's specified temperature and pH range. This range is much lower than chlorine or quats, so using a chlorine test strip or a higher target would be wrong. Always check the specific product label and verify with the matching test kit.
