2 Introduction
2.1
Instrument description
The 916 Ti
‑
Touch is a compact titration system for volumetric titration.
This titrator combines in a single device the touch-sensitive color monitor
for convenient and efficient operation, the titration unit and as well as
depending on the product version an integrated stirrer interface for a pro-
peller 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 Dosimat
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 connector 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
