Labindia Karl Fischer apparatus has Storage Facility for 50 methods.

Karl Fischer Titrator (KAFI+)

Karl Fisher Titrator KAFI + complies with USP/BP/ASTM standards. There is a online leak correction available to check for any leaks before the run. 50 methods can be stored and the last 10 results can be stored and printed with all the required parameters.

Karl Fischer Titrator is based on variable speed magnetic stirrer with digital indication on back lighted liquid crystal LCD screen. Two tier password facility is given to protect stored methods from any misuse or unwanted change. There is also a PC compatibility software with built in balance interface.
