831 KF Coulometer
Determination of water content down to trace amounts
|
|
The 831 KF Coulometer has established
itself for the determination of very small amounts of
water. Besides its extremely compact design, the it fulfills
every Karl Fischer analysis task. The clear display provides
information about the relevant
titration parameters and gives an unmistakable presentation
of the course of titration in form of a curve showing µg
water against time. Improved coulometric generator cells
and reagents ensure interruption-free, reliable results
over a long period.
This favorably-priced coulometer version does not habe a built-in printer, but
otherwise corresponds exactly to the specifications of
the 756 KF Coulometer. |
The innovative solution: convincing arguments
- no titer determination is required in coulometry
- titration cells with or without diaphragm - it's
your choice!
- Metrodata VESUV Light, a PC program for backup and
database functions is included in the delivery package
- two RS 232C interfaces for communication with balance,
computer and external printer
- compatible with the 774 Oven Sample Procesor
- on-line control of reagent consumption versus time
- dialogue languages: English, French, German, Italian,
Portugese, Spanish, Swedish
- meets the requirements of ISO 900X and GLP
- ideal building block for titration networks with
the FDA 21 CFR Part 11 compliant PC program TiNet 2.5
- programmable service and validation intervals
- programmable upper limits for contents and reagent
consumption during automated analysis

Just push the button |
Connecting a 700
Dosino to the 831 KF Coulometer allows to siphon
off the contents of the coulometric cell and fill it
with fresh reagent. As the KF vessel remains closed,
no humidity can enter the system. Within a minimum of
time the analysis cell is conditioned again. |
Very flexible but easy to use |
Extensive flexibility and user-friendliness are no contradiction
in terms any more. The 831 KF Coulometer has two principle
working modes: The expert mode allows it to use all different
features of this high tech device. In the standard mode
just a few keystrokes are enough to start your analysis.
|
| The 831 KF Coulometer stores up to 100 different
methods in its internal memory. Methods can easily be transferred
and reloaded via the RS 232C interface to a PC. |
If there is moisture in it, Metrohm titrators will
find it
