Description
A chemical test kit called the HI38020 measures the levels of free and total chlorine 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. All of the equipment and reagents required to complete both analyses, including the Checker® disc for precise measurement, are included with the HI38020. There are enough reagents in the test kit to conduct about 200 tests.
Features in plain sight
entire setup
- The test kit comes with all necessary supplies, including the glass vials, plastic pipette, reagent packets, and Checker® disc.
- heightened clarity
- To 0.02 mg/L resolution, readings between 0.00 and 0.70 mg/L are calculated.
- Resolution of 0.1 mg/L is used to determine readings between 0.0 and 3.5 mg/L.
- To a resolution of 0.5 mg/L, readings between 0.0 and 10.0 mg/L are calculated.
- Replacement chemicals on hand
When reagents run out, a new kit does not need to be purchased. You can order the HI38020-200 to swap out the reagents that come with the kit. This package of reagents contains 100 packets each of the reagents HI93701-0 for free chlorine and HI93711-0 for total chlorine.
Relevance of Use
In processes including drinking water and wastewater treatment, pool and spa sanitization, and food processing and sterilization, chlorine is the most often utilized water disinfectant. Only a portion of the original amount of chlorine (free chlorine) is left when chlorine present in water binds with bacteria and stops acting as a disinfectant. Water will have an unpleasant taste and odor and its ability to disinfect will be reduced if the free chlorine content is incorrect in relation to pH.
Free chlorine loses some of its disinfectant properties when it interacts with ammonium ions and organic molecules to produce chlorine compounds. Combination chlorine is made up of chloramines and chlorine compounds. Total chlorine is the sum of combined chlorine and free chlorine. While combined chlorine has far higher stability and lower volatility than free chlorine, the latter has a much stronger disinfection potential.
