Chemical test kit to measure free and total chlorine in the low, medium, and high range
HN/038020 - Free and Total Chlorine Low, Medium and High Range Test Kit
The HN/038020 is a chemical test kit that uses the DPD method to measure free and total chlorine in the low, medium, and high range.
The HN/038020 is supplied complete with all of the reagents and equipment necessary to perform approximately 200 tests.
- Pre-made reagents for ease of use
- All reagents marked with expiration date and lot number for traceability
- Checker disc for more accurate determination
Details
The HN/038020 is a chemical test kit that determines the free and total chlorine concentration in three ranges: 0.00 to 0.70 mg/L, 0.0 to 3.5 mg/L, and 0.0 to 10.0 mg/L.
The HN/038020 is supplied with all of the necessary reagents and equipment to perform both analyses, including the Checker disc for accurate determination.
The test kit contains enough reagents for perform approximately 200 tests.
Features at-a-glance
- Complete setup
- All required materials are included with the test kit, such as the glass vials, plastic pipette, reagent packets, and Checker® disc.
- High resolution
- 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.
- Readings from 0.0 to 10.0 mg/L are determined to 0.5 mg/L resolution.
Replacement reagents available
There is no need to buy a new kit when reagents are exhausted. The HN/038020-200 can be ordered to replace the reagents supplied with the kit. This reagent set comes with 100 packets of HN/093701-0 free chlorine reagent and 100 packets of HN/093711-0 total chlorine reagent.
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.
