Titration method Volumetric Karl Fischer reagent titration method
Titration control method Intermittent addition of titrant while approaching the end point. (1) Control using a waiting interval timer of 1 - 99sec (INTERVAL). Titration stops when there is no change in the electrode potential during this interval. (2) Control by titration timer. (T-TIMER: 1 - 99min.)
