Multi-parameter measuring instruments are multifunctional. A multi-channel system allows multiple parameters to be recorded simultaneously. A simple user interface and a robust housing not only allow for use in the laboratory, but also in the field of water control or profile measurements. Thanks to a high storage capacity and an easy transfer of the information via USB, the processing and evaluation of the data is straightforward. In addition, a GLP-supporting function, a graphical representation of the data and several connection possibilities are available for further sensors or measuring modules. The pH, conductivity, temperature or redox potential can also be measured in the laboratory. The practical combination of simple operation and clear presentation, high, flexible functionality and large storage volume makes the multi-parameter measuring instruments a necessary purchase for a good analysis!
