Despite its low price, the newest member of Metrohm's Karl Fischer product line masters a large number of analytical tasks
The 831 KF Coulometer determines even ultratraces of water with great accuracy.
Other features are its compact design, flexibility, and easy operation.
On the backlit LCD screen, you can graphically follow the course of the Karl Fischer water determination (ug water as a function of time).
Flexible and easy to use The 831 KF Coulometer is ideal for routine operations.
Even with its extensive capabilities, it is easy to operate.
At your disposal are an expert mode as well as a standard mode.
The expert mode allows the use of all the features of this high-tech device.
In the standard mode, only functions needed in routine work are accessible; operation in this mode is simple and requires very few keystrokes.
Automatic reagent exchange.
Connecting a 700 Dosino to the 831 KF Coulometer allows you 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 again conditioned.
Freedom of choice.
The coulometric cell without diaphragm works with only one reagent and is insensitive to interferences.
However, as not all applications can be solved with this cell, Metrohm also offers a cell with diaphragm.
Method storage.
The 831 KF Coulometer stores up to 100 different methods in its internal memory; these methods can easily be transferred to and reloaded via the RS- 232C interface from a PC.
Karl Fischer ovens.
Use of a KF Oven is recommended for samples that cannot be introduced directly into the KF cell.
The 832 KF Oven can be used if only a few samples need to be processed.
However, the 774 oven sample processor is the ideal solution for analysis of a large number of samples.
When combined with the 831 KF Coulometer, this sophisticated sample changer allows fully automated water determinations in up to 35 samples.
The analysis system can be operated as a stand-alone unit, or it can be completely controlled by Metrohm titration software.
