890 Titrando
Up to three control instruments (Titrando, Dosing Interface, USB Sample
Processor, etc.) can be controlled via USB connection during operation
with the 900 Touch Control.
You can request information on special applications in the "Application
Bulletins" and "Application Notes", available free of charge through the
responsible Metrohm representative. Various monographs on the subjects
of titration techniques and electrodes are also available.
Updating the device software is described in the Help for the correspond-
ing PC software.

1.3 Titration modes – Measuring modes – Dosing com-
mands
The 890 Titrando supports the following titration modes, measuring
modes and dosing commands:
￭ KFT
Volumetric water content determination according to Karl Fischer.
Measuring modes:
– Ipol (voltametric measurement with selectable polarization cur-
rent)
– Upol (amperometric measurement with selectable polarization
voltage)
