    5 | Measurement Basics G 1409 Total dissolved solids / TDS measurement The total dissolved solids measurement - TDS measurement - determines the total dissolved solids, which also called evaporation residue, based on the conductivity and a conversion factor CtdS of the total dissolved solids. Well-suited to conduct simple concentration measurements of salt solutions.

    G 1409 Measurement Basics | 5 Electrodes / measuring cell 5.5.1 Design There are basically two different types of measuring cells: 2-pole and 4-pole measur- ing cells. Control and/or evaluation take place in a similar manner; the 4-pole measur- ing cells can compensate well for polarisation effects and contamination to a certain degree with the more elaborate measuring processes.
