Extech CL500 Free And Total Chlorine Meter Details

Made for use in measurements of discharge water from water treatment plants, public drinking water and cooling towers and free chlorine measurements in swimming pools and other cooling water applications, the Extech CL500 provides accurate, fast measurements of free and total chlorine from 0.00 to 3.50ppm.

The CL500 can be used to measure total residual chlorine in all forms, including dissolved free chlorine, chloramines, hypochlorous acid and hypochlorite ion. To use, a sample of the water is inserted into a testing bottle along with a reagent tablet; the CL500 then measures the overall content of chlorine via its built in electrode.

Measurements taken using this chlorine meter are carried out with a high degree of accuracy (0.02ppm@1.00ppm) and with resolution of 0.01ppm. The method of measurement is approved by the U.S Environment Protection Agency (EPA) as an acceptable method for wastewater compliance monitoring of total chlorine levels.
