The 756 KF Coulometer continues Metrohms established line of Karl Fischer instruments for the determination of low-level water contents. Despite its compact construction this instrument leaves no wishes unfulfilled. It comes equipped with a built-in printer and two RS 232C interfaces which allow communication with a balance, external printer and/or computer. This latest addition to the Karl Fischer range guarantees accurate and reproducible results even for water contents in the lower micro range. The dialogue languages English, French, German, Spanish, Portuguese, Swedish and Italian are standard, as is the backlit screen with its graphics capabilities. The screen not only provides a clear presentation of the parameters, but also shows graphically the course of the KF determination as µg water versus time. This facilitates the assessment of the determination and is a great help in method development and validation.
Depending on the amount of data that are to appear on the instrument display, large or small fonts can be selected.
A user list can be entered; the name selected from this list appears in the result report, which can be freely configured by simply selecting the lines containing the desired information.
Using the optional Remote Box you can connect a barcode scanner and a PC keyboard to the 756 KF Coulometer.
The KF reagent can be monitored with regard to the number of determinations carried out, its useful life span, drift value or capacity. Whenever the reagent has to be exchanged the corresponding request is issued automatically. To avoid mishaps of any kind there is the additional possibility of setting limits for the sample weight or volume and for the result. If one of these quantities lies outside the set limits, the corresponding warning message appears in the display and report and the Remote interface emits a signal.
One press of a button for renewing the KF solution
If a Dosino is connected to the 756 KF Coulometer the spent solution can be siphoned off by simply pressing a button. This starts a preprogrammed sequence which runs in the background and transfers the titration vessel contents via the Dosino into the waste bottle. Subsequently, fresh reagent is added to the KF cell. As the cell does not need to be opened during this operation, no humidity enters the cell, which therefore is ready for the next determination in a very short time.
