Dosing and titration with externally connected piston burettes and
titrators

Requirements

5.1

From software version 1_18_809_236 onwards, it is possible to carry out pre-dosing and titration with externally
connected titrators and piston burettes on the TitroLine

®

7000, 7750 and 7800 titrators.

The following devices can be connected to the titrator with the connection cable TZ 3094:



TITRONIC

®

300 and TitroLine

®

5000 from version 2_18_619_25



TITRONIC

®

500, TitroLine

®

6000, 7000, 7750 and 7800 (all versions)

For the connected devices you can set the addresses from 0 to 15:



The device addresses are set in advance and the device is switched off and on once



It is important that different addresses are set for more than one connected device

In one method, pre-dosing can be performed with one or two connected devices:



A titration (with pre-titration) can then be carried out with another device.



Therefore, in one method up to three devices can be controlled externally.

The electrodes can only be connected to the central titrator.

Dose with external piston burettes/titrators

5.2

In this case, a connected T 300, iodine solution (20 ml volume) should be added and after a waiting period of 60
seconds, the titration with sodium thiosulfate should be performed on EQ with the TitoLine
