Title goes here.

The FC7 is a panel mounted, ready to use Free Chlorine Sensor. It is designed to monitor free chlorine in drinking water, rinse water,

cooling water or other fresh water samples from 0.05~10ppm Cl2 as the standard range or 0.01~5.00ppm with the low range sensor.

The FC7 is compliant with EPA method 334.0 for measuring drinking water.

Free chlorine exists in solution as pH dependent ratio of
hypochlorous acid (~100% at pH 5) and hypochlorite ion (~100% at pH 10). Free Chlorine is the sum of the Hypochlorous acid and Hypochlorite ion in the sample. The Free Chlorine Sensor measures only the hypochlorous acid component of the free chlorine and the analyzer calculates the balance using either the
measured or a user defined fixed value. The use of the pH sensor provides accurate compensation for samples between pH 6 and
pH 9.5 and eliminates the need for an expensive sample
conditioning system to control the pH of the solution.
