Chlorine Test Kits 

Free Chlorine AccuVac Test Kit

The most widely used disinfectant for drinking water, chlorine is also important for sanitizing swimming pools, cooling towers, other industrial equipment, and in the treatment of municipal wastewater. Its measurement and control are vital for both safety and economic reasons. Many Hach chlorine tests have been accepted by the USEPA for reporting purposes. Test kits containing DPD colorimetric reagent are used most often for monitoring potable water, swimming pools, and waste effluent. Powder DPD dissolves and reacts with chlorine more quickly than tablet-form DPD, giving more accurate results. Powder DPD also has a considerable advantage over orthotolidine, a hazardous substance sometimes used as a chlorine test reagent. It is more stable than liquid DPD reagents, providing more reliable results. Kits for determining higher levels of chlorine use thiosulfate to measure chlorine titrimetrically.
