TEST/ High Level Chlorine Test Kit, 0 - 1000 ppm
The High Level Chlorine test strip tests levels of free chlorine in a solution, in steps of 0-50-100-250-500-1,000 ppm, giving results in just seconds. This test strip is used where higher levels of disinfection are required. The higher range provides a much higher degree of certainty that all organisms are either killed or rendered ineffective.
