904 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

1.2 Instrument description
The 904 Titrando has the following characteristics:
￭ Operation
Operation is carried out by means of a touch-sensitive Touch Control
or with high-performance PC software.
￭ Dosing
An internal dosing drive for exchange units.
￭ MSB connectors
Four MSB connectors (Metrohm Serial Bus) for connecting dosing devi-

Two USB connectors, through which devices such as printers, PC key-
boards, barcode readers or additional control instruments (USB Sample
Processor, Titrando, Dosing Interface, etc.) can be connected.
￭ Measuring interface
Depending on the model version, one or two measuring interface(s).
Each measuring interface has one measuring input each for:
– a potentiometric electrode (pH, metal or ion-selective electrode)
– a separate reference electrode
– a temperature sensor (Pt1000 or NTC)
– a polarizable electrode
– an iConnect (measuring interface for electrodes with integrated
data chip, so-called iTrodes)
