The TitrIC flex II system is used for the fully automatic analysis of water samples using direct measurement, titration, and ion chromatography. The following parameters are determined within a very short time: temperature, conductivity, pH, acid capacity, and in parallel, the concentrations of individual anions and cations with the resulting water hardness and ion balance. Further Metrohm instruments can be incorporated in the existing system at any time and used to measure additional parameters. This Application Bulletin describes in detail the installation instructions for the TitrIC flex II system.
