CHLORINE IN CLEAN WATER

Chlorine is the most commonly used water disinfectant in applications such as drinking water and wastewater treatment, swimming pool and spa sanitation and food processing and disinfection. Chlorine in water binds to bacteria, leaving only a portion of the original amount (free chlorine) to continue disinfecting. If the level of free chlorine is not in line with the pH, the water will have an unpleasant taste and odor due to the reduced disinfecting ability of chlorine.

Free chlorine reacts with ammonium ions and organic compounds to form chlorine compounds; reducing the disinfecting power compared to free chlorine. Chlorine compounds along with chloramines form combined chlorine. Combined chlorine and free chlorine form total chlorine. While free chlorine has a much higher disinfecting power, total chlorine is more stable and less volatile.

FAST RESIDUAL CHLORINE MEASUREMENT BY COLORADO DISC METHOD

– Measuring range 0.00 to 0.70 mg/L Cl₂ in increments of 0.02 mg/L

– Measuring range 0.0 to 3.5 mg/L Cl₂ in increments of 0.1 mg/L

– Scale 0.0 to 10.0 mg/L Cl₂ in increments of 0.5 mg/L

THE PERFECT SET WITH NO EXTRA PURCHASES

HI38020 Supplied with reagents for 100 free chlorine measurements and 100 total chlorine measurements and complete accessories.

REAGENTS ARE CLEARLY LABELED AND QUANTIFIED

– 1 reagent pack for 1 measurement, easy to use.

- Cost savings.

– Reagents can be purchased when they run out without having to repurchase the entire product code: HI93711-01 (total chlorine) or HI93701-01 (free chlorine)
