CHECKIT® Comparator Water Balance Chlorine DPD/pH/Cyanuric acid/Calcium hardness/Total Alkalinity

Water Balance in private pools and spas is the focus of this test kit for controlling the most important parameters of water quality. These include above all disinfectants based on chlorine (free, bound and total chlorine) and the pH value. Cyanuric acid, as a carrier substance of organic or stabilised chlorine, is important for the water balance and binds part of the chlorine content measured by DPD 1 at higher concentrations. High calcium hardness can cause turbidity. If the value is too low, the water becomes aggressive and damage to the building fabric is the result. Alkalinity-M describes the ability of the water to keep the pH value stable when acid or lye is added.
