Karl Fischer titration
KF Coulometer
756/831 KF Coulometer
The Metrohm KF Coulometers are suitable for precise
water determinations in the trace range (1ppm...10%).
They are available with two different types of generator
electrodes. The diaphragm-less generator electrode
requires only one reagent and is practically maintenance-free.
The use of the generator electrode with
diaphragm is preferred for the following applications:
very low water content (< 100 µg water absolute),
when ketone reagents are used or with a high content
of solubility promoter (> 10%).
With or without printer – choose as you prefer! The
756 KF Coulometer is equipped with a built-in thermal
printer. However, just like the 831 KF Coulometer,
you can also connect an external printer or connect
the instrument to a PC, in which case you can choose
between the Metrodata Vesuv and tiamo software.
With our KF Coulometers you receive a complete titration
cell and extensive accessories. KF Coulometers
with the diaphragm generator electrode are delivered
with the 728 Magnetic Stirrer as part of the accessories.
