1 Introduction
1.1The Titrando system
The Titrando is the heart of the modular Titrando system. Operation is carried out either by Touch Control with a touch-sensitive screen ("standalone titrator") or by a computer with a corresponding software.
A Titrando system can contain numerous kinds of a variety of instruments. The following figure provides an overview of the peripheral devices you can connect to the 905 Titrando.

1.2 Instrument description |
|
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 corresponding PC software.
1.2Instrument description
The 905 Titrando has the following characteristics:
Operation
Operation is carried out by means of a touch-sensitive Touch Control or with high-performance PC software.
MSB connectors
Four MSB connectors (Metrohm Serial Bus) for connecting dosing devices (Dosimat with exchange unit or Dosino with dosing unit), stirrers, titration stands and Remote Boxes.
USB connectors
Two USB connectors, through which devices such as printers, PC keyboards, 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)

1 Introduction |
The 905 Titrando supports the following titration modes, measuring modes and dosing commands:
DET
Dynamic equivalence point titration. The reagent addition is carried out in variable volume steps.
Measuring modes:
–pH (pH measurement)
–U (potentiometric voltage measurement)
–Ipol (voltametric measurement with selectable polarization current)
–Upol (amperometric measurement with selectable polarization voltage)
MET
Monotonic equivalence point titration. The reagent addition is carried out in constant volume steps.
Measuring modes:
–pH (pH measurement)
–U (potentiometric voltage measurement)
–Ipol (voltametric measurement with selectable polarization current)
–Upol (amperometric measurement with selectable polarization voltage)
SET
Endpoint titration at one or two specified endpoints. Measuring modes:
–pH (pH measurement)
–U (potentiometric voltage measurement)
–Ipol (voltametric measurement with selectable polarization current)
–Upol (amperometric measurement with selectable polarization voltage)

1.3 Titration modes – Measuring modes – Dosing commands |
|
MEAS
The following measuring modes can be selected for measurements:
–pH (pH measurement)
–U (potentiometric voltage measurement)
–Ipol (voltametric measurement with selectable polarization current)
–Upol (amperometric measurement with selectable polarization voltage)
–Conc (concentration measurement with or without standard addition)
–T (temperature measurement)
STDADD
The measuring modes for standard addition are listed separately only in tiamo™. In Touch Control they are integrated in the measuring mode MEAS Conc.
The following measuring modes can be selected for measurements:
–auto (automatic addition of the standard addition solution by specifying a potential difference)
–dos (automatic addition of the standard addition solution by specifying the individual volume increments)
–man (manual addition of the standard addition solution)
CAL
Electrode calibration. Measuring mode:
–pH (calibration of pH electrodes)
–Conc (calibration of ion-selective electrodes)
ELT
Electrode test for pH electrodes.
This mode is listed separately only in tiamo™. In Touch Control, the electrode test is a component part of the CAL calibration mode.
Dosing commands
The following commands for dosing can be selected:
–PREP (rinsing the cylinder and tubings of an exchange unit or dosing unit)
–EMPTY (emptying the cylinder and tubings of a dosing unit)
–ADD (dosing a specified volume)
–LQH (carrying out complex dosing tasks with a Dosino)

1.5Safety instructions
WARNING
This instrument may only be operated in accordance with the specifications in this documentation.
This instrument has left the factory in a flawless state in terms of technical safety. To maintain this state and ensure non-hazardous operation of the instrument, the following instructions must be observed carefully.
The electrical safety when working with the instrument is ensured as part of the international standard IEC 61010.
WARNING
Only personnel qualified by Metrohm are authorized to carry out service work on electronic components.
WARNING
Never open the housing of the instrument. The instrument could be damaged by this. There is also a risk of serious injury if live components are touched.
There are no parts inside the housing which can be serviced or replaced by the user.
Mains voltage
WARNING
An incorrect mains voltage can damage the instrument.
Only operate this instrument with a mains voltage specified for it (see rear panel of the instrument).
