Check bleach solution strength in 30 seconds.
Activate High-level Chlorine Test Strips ensure the adequacy of diluted hypochlorite bleach-disinfectant solutions in just 30 seconds. The test strips offer a broad range, measuring available chlorine levels at 0; 1,000; 2,500; 5,000; 7,500; and 10,000 ppm for disinfection purposes. A desiccant-lined vial with an ergonomic snap closure helps keep strips fresh. The 50 strips per vial should be used within two years of initial opening of the vial. Record the opening date on the lower right side of the vial label.
