Aquacon - Model CL2/CHLOR - Process Analyzers Brochure

The AQUACON CL2 and AQUACON 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-p-phenylendiaminsulfat (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 AQUACON CL2 determines the concentration of free chlorine or of total chlorine. The AQUACON CHLOR determines the concentration of free chlorine and of total/bounded chlorine.
