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.
Each set has 100 strips.
- 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.
