HI711 Hanna Total Chlorine Checker

With the Hanna Total Chlorine Checker you can check for total chlorine at the touch of a button and get instant results.

Chlorine is the most common water disinfectant. Once in water it presents as free chlorine and total chlorine;

  • Free chlorine is the chlorine that is available in the water to tackle bacteria. As the process of disinfection takes place, the levels of free chlorine will reduce.
  • Total chlorine is the measurement of free and used chlorine (or Chlorimines) in the water. If the total chlorine is high but the free chlorine is low or non-existent, then there is insufficient chlorine in the water to deal with the levels of contamination. By checking for the two as part of a rigorous testing procedure, adjustments in chlorine levels can be made quickly and easily and a high level of disinfection can be easily maintained.
