917 Coulometer
2 Introduction
2.1 Instrument description
The 917 Coulometer is a compact titration system for coulometric Karl
Fischer titration. This newly designed titrator combines in a single device
the touch-sensitive 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 917 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 sys-
tem.
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
2.1.1 Titration and measuring modes
The 917 Coulometer supports the following titration and measuring
modes.
