Precise and economical

The 831 KF Coulometer sets a new standard concerning price-performance ratio. Despite its low price the youngest member of our Karl Fischer product line masters a large number of analytical tasks. The instrument determines even ultra traces of water with great accuracy. Compact design, flexibilty and ease of use are further advantages of the 831 KF Coulometer.

831 KF Coulometer

The innovative solution

  • new controller guarantees precision down to the lower µg range
  • backlit graphic screen
  • on-line control of reagent consumption versus time
  • two RS 232C interfaces for communication with balance, computer and external printer
  • dialog languages: English, German, French, Spanish, Italian, Portuguese, Swedish
ISO 900X and GLP
  • built-in clock
  • 8-digit date format (YYYY-MM-DD)
  • programmable service and validation intervals
  • programmable upper limits for contents and reagent consumption during automated analysis
Automatic reagent exchange 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 principal working modes: The expert mode allows to use all features of this high tech device. In the standard mode just a few keystrokes are enough to start your analysis.
Freedom of choice The coulometric cell without diaphragm works with only one reagent and is quite 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. Methods can easily be transferred to and reloaded via the RS 232C interface from a PC.

If there is moisture in it, Metrohm titrators will find it
