ชุดทดสอบคลอรีนอิสระ Free Chlorine test

รุ่น HI3875 แบรนด์ HANNA 

Description

The HI3875 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.
