- Free chlorine reacts with ammonium ions and organic compounds to form chlorine compounds resulting in diminished disinfecting capabilities compared with free chlorine. These chlorine compounds together with chloramines form combined chlorine. Combined chlorine and excess free chlorine together result in total chlorine. While free chlorine has a much higher disinfectant potential, combined chlorine has a much higher stability and has a lesser volatility. There should be sufficient levels of unreacted free chlorine for adequate disinfection, but not so much as to become harmful. Test kit comes with color comparison cube, 20ml reagent 1 and 15ml reagent 2. Colorimetric method. Range: 0.0-2.5 milligram per liter. Smallest increment: 0.5 milligram per liter. DPD chemical method. Number of tests approximate 50. Weight: 176 grams.
