The ECD DC80 DeChlorination Analyzer is a panel mounted, ready to use DeChlorination Analyzer. It is designed to monitor very low levels of Total Chlorine water to measure that chlorine has been removed within an allowable level before discharging or releasing water into the environment. The DC80 DeChloinration Analyzer has all of the advantages of ECD’s TC80 Total Chlorine Analyzer and uses a “zero shift” strategy to make the measurement. Since the total chlorine amperometric needs some amount of chlorine for a stable reading, the ECD DC80 pump supplies a constant 3 to 5 ppm of total chlorine and the DC80 DeChlorination Analyzer “zeros” out this offset to measure the difference of the water to be measured compared to the total chlorine supplied.
