The FREE Chlorine test strip tests levels of FREE chlorine in a
solution. The bottle has easy to read color blocks at 0, 50, 100, 250, 500, and
1,000 ppm. This test strip is very easy to use, and gives 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. It is ideal for daycares,
senior homes, and cruise lines sanitation requirements.
