Introduction
Congratulations on your purchase of the ExStik
The CL200 is a revolutionary first of its kind measurement device that
offers direct reading of Total Chlorine from 0.01 to 10.00 ppm. The
electrode method employed by the ExStik
Environmental Protection Agency (EPA) as an acceptable method for
wastewater compliance monitoring of total chlorine. For this type of
electrode method, a reagent tablet must be added to the measurement
solution before testing. The advantages of the CL200 to the user
include: Easy to use and maintain, high accuracy, self-calibration, and
fast response. The CL200 offers simultaneous Chlorine and
Temperature displays and a 15-reading memory storage. Careful use
and maintenance will provide years of reliable service.
Applications
The CL200 can be used wherever a measurement of the total chlorine
in water is needed. This is also referred to as total residual chlorine. It
measures the total of all chlorine present in all forms, including
dissolved free
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.
