Coulometric Karl Fischer Titration Controller

Karl Fischer titration is a classic titration method in analytical chemistry that uses coulometric titration to determine trace amounts of water in a sample.

Coulometric Karl Fischer Titration Controller

Contacts and Location


  • Perfect for determining water content in petroleum products, pesticides, detergents, foods, pharmaceuticals, chemicals, solvents and more.
  • Easy method programming and simple operation.
  • Up to ten customized procedures can be stored and easily recalled.
  • Perform up to four titrations simultaneously, thanks to separate interconnectable 275KF titration modules.
  • Time/date stamp on printouts to meet GLP requirements.
  • Calculate statistical data for up to five results.
  • Simple to interface with computer or printer. Automatically prints titration reports.
  • The system automatically compensates for the drift rate of ambient moisture entering the cell.
  • Automatically gives message when reagents have been depleted. Press a single key for reagent condition.
