TitroLine® 7800

Automatic Titrator with IDS technology for exchangeable heads for potentiometry and KF

The Titroline® 7800 enhanced the universal features of the TitroLine® 7750 with an additional IDS measurement socket. Hence the TitroLine® 7800 can perform potentiometric titrations with analog and IDS electrodes up to volumetric KF titrations. The digital (IDS) measurement socket allows the connection of various digital sensors, such as for measuring of conductivity.
