What is chlorine analyzer?
Non-reagent Type Free Available Chlorine Sensor Unit FC800D The FC800D is a non-reagent type chlorine analyzer and measures free chlorine continuously. It is suitable for free chlorine control and monitoring in drinking water.
How does a CL17 work?
The Hach CL17 Chlorine Analyzer uses colorimetric DPD chemistry to monitor water continuously for free or total residual chlorine. The CL17 analysis method is not affected by changes in chlorine concentration, sample pH, temperature, flow or pressure, thus offering more accuracy than other methods in today’s market.
What is residual chlorine analyzer?
Residual chlorine is one of the most important measurements for the effective monitoring of cooling, potable and industrial water treatment processes. The AW401 residual chlorine monitor control and monitors residual chlorine levels accurately and affordably.
How do you calibrate a CL17 chlorine analyzer?
1) Place a container of zero reference water above the analyzer with at least two feet of head and plumb the analyzer so the sample flow can be shut off and the zero reference water substituted. Let the analyzer run on the zero reference water for at least 10 minutes. 2) Key in the number 0 and then press the ZERO key.
What are the two types of online chlorine analyzers?
The two most common methods for on-line chlorine analysis are amperometric and colorimetric detection.
How is free chlorine measured?
The test kit can be used to measure free chlorine and/or total chlorine, with a range of 0 – 3.5 mg/L, equivalent to 0 – 3.5 ppm (parts per million). Digital colorimeters are the most accurate way to measure free chlorine and/or total chlorine residual in the field in developing countries.
How do you clean Hach CL17?
What is the cleaning procedure for the CL17 colorimeter? The colorimeter measuring cell may collect sediment or develop a film growth on the inside walls. Cleaning with an acid solution and a cotton swab on a monthly basis is recommended. Depending on sample conditions, it may be necessary to clean the cell more often.
How do I prime my CL17?
Arrow down to the MAINT menu and press enter. You will see the word PRIME on the display – press enter. You will see the number 38 displayed and below it the word PRIME will flash. The CL17 will count down from 38 to zero.
What is the difference between free chlorine and residual chlorine?
These hypochlorite ions are called as free chlorine. This free chlorine is responsible for the chlorination of the microbes in water. All the free chlorine is not consumed in the chlorination. This remaining chlorine is called residual chlorine.
