Process analyzers for the determination of Chlorine
The WATERLINE CL2 and WATERLINE CHLOR process photometers can be used for the monitoring and control of the chlorine concentration in water. Measurement principle is the photometric determination of chlorine by dosing a special reagent based on N,N-Diethyl-pphenylendiaminsulfat (DPD) to a buffered water sample. The wine-red colour formed as a result of the reaction is detected by a monochromatic photometric detection system. The WATERLINE CL2 determines the concentration of free chlorine or of total chlorine. The WATERLINE CHLOR determines the concentration of free chlorine and of total/bounded chlorine. The analyzers consist of a control unit with touchscreen and an analysis unit with measuring chamber, valve, dosing pumps and all required tube connections. The control unit includes a microprocessor which controls the automatic measurement incl. sampling, rinsing, reagent dosing and surveillance of the photodetection system. Main applications for the photometers are the monitoring of the chlorine concentration in drinking water, cooling water and swimming pool water.
