Working Principle
The GV30 Automatic Karl Fischer Moisture Titrator adopts the classical Karl Fischer titration principle, where water in the sample reacts chemically with Karl Fischer reagent.
During measurement, the instrument automatically adds Karl Fischer reagent through a high precision burette. The dual platinum electrode continuously monitors the reaction endpoint based on electrical signal changes.
When all water molecules have reacted completely, the system automatically detects the endpoint and calculates the water content according to the consumed reagent volume.
The intelligent control system automatically adjusts titration speed, compensates for solvent resistance differences and provides accurate moisture measurement results.
