Promaster 25-123, Chlorine Test Strips, 100/PK

25-123, Chlorine Test Strips, 100/PK are used to determine if bleach-based sanitizers are at the appropriate concentration for use in sanitizing food-processing equipment. You should dip the strip into a solution (a dilution of bleach for immediate use), and then compare to the color chart included with the product. You should be able to define, in seconds, whether your bleach cleaning solution is at the strength recommended for safe food handling or not. The color indicated will either tell you, for example, that the solution is "strong enough to kill bacteria” at 200 ppm, or alternatively, the solution is "close to inactive” at 10ppm. Do not dip the test strip directly into a bleach container. Also, consult your local health department to ensure you are meeting the appropriate standard.
