Free and Total Chlorine Test Kit (Low and Medium Range)
The HI38017 is a chemical test kit that uses N,N Diethyl-1,4 Phenylenediamine Sulfate (DPD) to measure free and total chlorine in the low and medium range. The HI38017 is supplied complete with all of the reagents and equipment necessary to perform 200 tests. The HI38017 is a chemical test kit that determines the free and total chlorine concentration in two ranges: 0 to 0.7 mg/L and 0 to 3.5 mg/L. The HI38017 is supplied with all of the necessary reagents and equipment to perform both analyses, including the Checker® disc for accurate determination.
• All reagents marked with expiration date and lot number for traceability
• Checker® disc for more accurate determination
• Pre-made reagents for ease of use
• All required materials are included with the test kit, such as the glass vials, plastic pipette, reagent packets, and Checker® disc.
• Readings from 0.00 to 0.70 mg/L are determined to 0.02 mg/L resolution.
• Readings from 0.0 to 3.5 mg/L are determined to 0.1 mg/L resolution.
Replacement reagents available
• There is no need to buy a new kit when reagents are exhausted. The HI38017-200 is the part number for replacement reagents.
• The HI38017-200 is supplied with 100 packets each of HI93701-0 free chlorine and HI93711-0 total chlorine reagents.
Significance of Use
• Chlorine is the most commonly used water disinfectant in applications such as drinking water and wastewater treatment, pool and spa sanitization, and food processing and sterilization. Chlorine present in water binds with bacteria, leaving only
a part of the original quantity (free chlorine) to continue its disinfecting action. If the free chlorine level is improper with respect to pH, water will have an unpleasant taste and odor and the disinfecting potential of the chlorine will be diminished.
• Free chlorine reacts with ammonium ions and organic compounds to form chlorine compounds; this results in diminished disinfecting capabilities compared with free chlorine. Chlorine compounds together with chloramines form combined chlorine.
Combined chlorine and free chlorine together result in total chlorine. While free chlorine has a much higher disinfectant potential, combined chlorine has a much higher stability and lower volatility.
