Iodine Test Strips
The Iodine test paper detects Iodine in solutions in increments of 0, 12.5, 25, & 50 ppm. Disinfection with Iodine occurs between 12.5 ppm and 25ppm. This is an older method for sanitizing utensils and dishware used in the restaurant trade. To use, remove one of the strips from the vial and dip the strip into the solution for 60 seconds without agitation. Remove and compare immediately to the color chart on the side of the vial.
