3. Browse results on a PC in a LAN connection
Results data and curves can be displayed on a PC with no optional software.

4. GLP correspondent functions to support reliability of the titration results
Buret precision test, electrode calibration, reagent remaining volume indication, and other useful functions for maintenance.

5. Different titrations can run in parallel at the same time! (Option parts)
Up to four titration stations are available.
