The HI3887 is a quick check swimming pool test kit that measures free chlorine and pH. Free chlorine is measured using the DPD method; pH is measured using a visual pH indicator. This kit is equipped with all the necessary reagents and equipment to perform approximately 50 tests for free chlorine and 100 tests for pH.
Chlorine is one of the most commonly used disinfectants for drinking water, wastewater, and water used for pools and spas. It can be added to in various forms including calcium hypochlorite, sodium hypochlorite, or in some instances, chlorine gas. When added to water, chlorine creates hypochlorous acid (HOCl) which dissociates into hypochlorite ion (OCl–).
HOCl ↔ H+ + OCl–
hypochlorous acid ↔ hydrogen ion + hypochlorite ion
HOCl is the form of chlorine that acts as a stronger disinfectant as compared to OCl–. To ensure the added chlorine is effective at sanitizing, the pH of the water must be taken into account. Around pH 7.5, HOCl and OCl– are present in relatively equal amounts. Below pH 7.5, the equilibrium shifts to favor HOCl; above pH 7.5, the equilibrium shifts to favor OCl–. Depending on the application, addition of chlorine is effective when added to water with a neutral or slightly acidic pH value.
When chlorine is first added to water, it is available as free chlorine. The measurement of free chlorine signifies the amount available for disinfection. Once chlorine begins to sanitize bacteria and pathogens present in the water, it becomes combined chlorine; combined chlorine is no longer available to act as a disinfectant.
