The TitroLine 7800 extends the universal capabilities of the TitroLine 7750 by an additional IDS trade fair entrance. Thus, the TitroLine 7800 can perform potentiometric titrations with analog and IDS electrodes up to volumetric Karl Fischer titrations. The IDS fair entrance is multi-functional. Digital sensors can be connected to determine the pH and redox values, the conductivity as well as the dissolved oxygen.
