HI-3875 FREE CHLORINE TEST KIT
HI-3875
Chlorine is the most commonly used water disinfectant in applications that vary from treatment of drinking water and wastewater, pools and spas sanitization, to food processing and sterilization. DPD method. Range (0.0-3.5 mg/L).
The HI-3875 free chlorine, medium range test kit is equipped with all you need to determine free chlorine levels in water. 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.
