Description
The instrument of Coulometric Karl Fischer titrators is an used for Coulometric water determination according to Karl Fischer. The instrument is designed for usage as a titrator in analytical laboratories.Its main application field is volumetric titration. The present instrument is suitable for processing chemicals and flammable samples. The usage of this titrators therefore requires that the user has basic knowledge andexperience in the handling of toxic and caustic substances. Knowledge with respect tothe application of the fire prevention measures prescribed for laboratories is also mandatory. |
