Chlorine Residual Test Strips 0-10ppm Vial of 50

Low Level Chlorine Test Strip, 10ppm
The Low Level Chlorine test strip measures residual chlorine from 0-10ppm in increments of 0-0.5-1-3-5-10 in just seconds. This test strip detects residual levels of free chlorine. It is accurate within 5-10% of reading the color scale. The strip can also be used to test for chlorine in drinking water if this is a concern, however, our Residual Chlorine test strip, which measures up to 5ppm, may be a better suited option for testing residual in drinking water.
