Active Chlorine Bleach Test Strips, 0-2000 ppm [Vial of 100 Plastic Strips] Designed for Daycares and Senior Homes for Sanitizing and Disinfecting

The Active Chlorine test strip tests levels of free chlorine in a solution. The increments are 0, 25, 50, 200, 500, 800, 1500, 2000 ppm. The color chart has obvious color changes from blue to brown to orange. This test strip is very easy to use, and gives results in just seconds. The Active Chlorine test strips can be used in facilities where food preparation areas, equipment, and general disinfection are more strictly controlled. Specifically, this product was developed for use in daycare centers and senior homes, where a disinfection level slightly higher than that available using our High Level Chlorine strip is required. Instructions: Dip the Active Chlorine test strip into solution for 1 second. Remove strip and shake off excess water. After 1 minute, compare pad against color chart. (Note: color on the pad may not be uniform; this is normal.)
