917 Coulometer
2 Introduction
2.1 Instrument description
The 917 Coulometer is a compact titration system for coulometric Karl
Fischer titration. This titrator combines in a single device the touch-sensi-
tive color monitor for convenient and efficient operation, the magnetic
stirrer and the membrane pump for adding and aspirating solvents. The
upper side of the housing offers space for the titration cell. Thanks to its
compact construction, you can use the 917 Coulometer in a small space
as a stand-alone titrator.
You manage reagents, sensors, methods, etc. conveniently in the internal
memory of the coulometer. 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 system.
The integrated Ethernet connector is available to you should you wish to
connect your 917 Coulometer 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
