SI Analytics TitroLine® 7800

The TitroLine® 7800 enhanced the universal features of the TitroLine® 7750 with an additional IDS® measurement input. Hence the TitroLine® 7800 is able to perform potentiometric titrations with analogue or IDS® electrodes up to volumetric Karl Fischer titrations. The IDS® measuring input is multifunctional. Digital sensors for the determination of pH and ORP value, the conductivity up to the dissolved oxygen can be connected.
