100 PK Plastic Active Chlorine Bleach Test Strip, High Level Up To 2000ppm For Sanitizers and Disinfectants DESIGNED FOR DAYCARES & SENIOR HOMES!

The Active Chlorine test strip tests levels of free chlorine in a solution. The increments are 0, 25, 50, 200, 500, 800, 1500, 2000ppm. 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.)
