Karl Fischer Titration is the specific standard method for water content determination and gives accurate and precise results within minutes.
One Click™ User Interface
  • Large color touchscreen (VGA 5.7 in. color TFT, 640 x 480 pixel) with simple-to-understand and fast-to-operate One Click user interface
  • All users have their own homescreen with dedicated shortcut buttons (12 per user) to directly start specific routine tasks
  • User interface in English, German, French, Spanish, Italian, Chinese, Russian, Polish, Korean and Portuguese available
Diaphragmless Cell
  • Choice of a current generator cell with or without a diaphragm
  • Diaphragmless cell offers more convenience for most samples as there is no catholyte needed
  • Due to the unique design, the diaphragmless cell even meets the demands of very precise low water content determinations
Solvent Manager for Safe Handling
  • Protects users against contact with chemicals
  • Takes care of filling, draining and exchange of reagents
  • It is controlled by the titrator and full security is guaranteed by overflow protector in the waste bottle
PC software LabX™ Titration
  • Connectivity to LabX Titration PC software via USB or direct Ethernet (TCP/IP)
  • Full control over the titrator, secure database archiving, networking, efficient result management with control charts and individual search filters or rapid and clear method development for new applications
  • Complete traceability by providing user management, audit trail, method history and electronic signature
Flexible Data Export
  • Devices such as printers, memory sticks, USB hub or USB barcode readers can be connected via the USB port and are automatically recognized
