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.
Instructions:
Use dry fingers to remove one strip of test paper from the vial. Dip the strip into the solution being tested for 60 seconds without agitation. Remove and compare immediately to the color chart while strip is still wet. Color comparison will indicate approximate strength of the solution in parts per million (ppm) available Iodine.
