Introduction
Congratulations on your purchase of the ExStik CL200 chlorine tester. The CL200 is a revolutionary

Protection Agency (EPA) as an acceptable method for wastewater compliance monitoring of total
chlorine.
A reagent tablet* (supplied) must be added to the measurement solution before testing. The CL200
is easy to use and maintain and offers high accuracy and fast response. CL200 features include
simultaneous chlorine and temperature displays and a 15-reading memory. Careful use and

including dissolved free chlorine, chloramines, hypochlorous acid and hypochlorite ion. Typical
applications include measurements of discharge water from water treatment plants, public drinking
water supplies and cooling towers, and measurement of disinfectant properties in swimming pools
and cooling water applications.
