Potentiometric titrators
Titrando family
Depending on the model, the Titrando supports the
titration modes DET (dynamic equivalence point titration),
MET (monotonic equivalence point titration), SET
(titration to one or two predefined endpoints), KFT
(volumetric Karl Fischer titration) and pH-STAT.
Ion meter
With the measuring modes MEAS pH and MEAS
CONC not only pH, potential and temperature can be
measured. Direct concentration determination and
standard addition is also possible with ion-selective
electrodes.
Comprehensive liquid handling
Basic operations in daily laboratory work, such as
pipetting, transferring, dosing, dispensing and diluting
become perfectly easy thanks to the liquid handling
functions of the Titrando. No matter whether you connect
the Dosino directly to the Titrando or carry out
operations using a USB Sample Processor, both systems
guarantee the highest accuracy and precision in the
range from 10 µL to 100 mL.
Measuring input
The measuring interface of the Titrando features
a high-impedance input and an input for polarizable
electrodes, as well as a separate reference input and
an input for a Pt 1000 or NTC temperature sensor. The
resolution of the inputs is 0.1 mV or 0.001 pH. Up to
two galvanically separate measuring interfaces can be
installed.
MSB connection
With the four built-in MSBs (Metrohm Serial Bus) up to
4 Dosinos or Dosimats, 4 magnetic or rod stirrers and
4 remote boxes for automation can be controlled. This
means that the modular Titrando system is the most
flexible titration system on the market. Plug-and-play
functionality saves the manual configuration of peripheral
devices; the Titrando automatically recognizes the
connected device.
Intelligent electrodes «iTrodes»
The built-in memory chip makes it possible to store
important sensor data such as article and serial
number, calibration data, calibration history, working
life and calibration validity. All sensor data is read
in automatically on connection to an 857 Titrando.
This prevents editing confusion or errors. If the type of
electrode is different from that defined in the method,
then the user is informed. Monitoring functions allow
the exclusion of electrodes whose calibration data lies
outside the limits or whose calibration has expired.
If the sensor is used with different instruments, then the
calibration data stored in the chip makes the electrode
transferrable; it no longer needs to be recalibrated
each time that it is used with different instruments.
Operation – it's your choice
Touch Control is an ergonomic and modern operating
unit. You can hold it in your hand, put it on the bench
or mount it on the wall. Of course, the Titrando can be
operated from virtually any PC. If using the PC Control
software you can operate the Titrando by mouse click.
Look and operation are practically identical to Touch
Control. Methods and determinations are 100% compatible.In
addition to the PC Control software, the new
tiamo titration software is also available. In addition
to the standard functions for controlling a Titrando,
tiamo offers numerous other functions, such as a
client-server database or real parallel titration.
Automation without limits
Increasing numbers of samples, complicated sample
preparation steps and unattended overnight operation
soon call for the use of a sample changer. The Titrando
has the necessary intelligence for controlling sample
changers. No matter whether large or small sample
capacity, one or two workstations, measuring out the
sample, sample preparation, liquid handling, rinsing
and calibrating the electrodes – the new USB Sample
Processors offer a high degree of automation at an
economic price perfomance ratio.
USB connection
For communication with balances, printers and other
USB-capable devices two USB ports are available.
Laboratory balances can be connected via an RS-232
converter.
The Dosino – dosing on a minimum footprint
With the Titrando dosing is carried out with a Dosino
and an intelligent dosing unit which is mounted
directly onto the reagent bottle. A data chip contains
all the information on the reagent and dosing unit
that is required for titration. The dosing unit can be
exchanged in no time at all. Each dosing unit has its
own serial and cylinder numbers and comes with its
own individual certificate.
