Bartovation Extra High-Level Chlorine Test Strips, 0-10,000 ppm

These strips are ideal for testing the available chlorine in bleach solutions, making them great for high-level surface disinfection. Strong bleach can kill even the most resistant bacteria and viruses, even in the presence of blood or feces. You can check available chlorine levels at 0, 1000, 2500, 5000, 7500, and 10,000 ppm. Each test takes approximately 30 seconds. They are packaged in vials of 100 strips, with each vial lined with desiccant to maintain freshness. These broad-range test strips can handle high-level available chlorine testing of up to 10,000 ppm.
