1 Introduction
1.1 Instrument description
The 916 Ti-Touch is a compact titration system for volumetric titration.
This newly designed titrator combines in a single device the touch-sensi-
tive color monitor for convenient and efficient operation, the titration unit
and an integrated stirrer interface for a propeller stirrer. The upper side of
the housing offers space for the titrant and the titration vessel. The titrator
is standard-equipped for operation with an external dosing drive of the
800 Dosino type with a dosing unit. You can however also use a 805 Dos-
imat with an exchange unit. Thanks to its compact construction, you can
use the 916 Ti-Touch in a small space as a stand-alone titrator.
You manage titrants, sensors, methods, etc. conveniently in the internal
memory of the 916 Ti-Touch. You can also save your files externally
through the USB connector, e.g. on a USB flash drive. On this storage
medium you can not only store your methods and determinations, but
also create a backup together with all of the data and settings of your sys-
tem.
The integrated Ethernet connection is available to you should you wish to
connect your 916 Ti-Touch to a network. The network connection offers
you the following advantages:
￭ Saving data to a PC within the network
￭ Printing reports on a network printer
￭ Sending displayed messages as e-mails
1.1.1 Titration and measuring modes
The 916 Ti-Touch supports the following titration and measuring modes.
￭ DET
Dynamic equivalence point titration. The reagent is added in variable
volume steps.
Measuring modes:
– pH (pH measurement)
– U (potentiometric voltage measurement)
– Ipol (voltametric measurement with selectable polarization cur-
rent)
– Upol (amperometric measurement with selectable polarization
voltage)
