Precision Laboratories Chlorine Test Strips produce a distinct color change over the entire range from blue to brown to orange, giving results in just seconds.
Our CHL-300 is almost identical to our CHL-200 test strip but with one extra increment.
CHL-1000 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.
Our CHL-10000 test strip is great for environments requiring high levels of sanitation/disinfection, such as hospitals.
