  • The large color LCD (8-inch wide) provides easy operations and better view of screen
  • Direct operations and maneuverability is now made possible with Touch screen LCD.
  • Simultaneous two titrations can be controlled individually. (JP Patent No. 2138712)
  • Built-in Compact Flash (CF) card slot for an additional user interface.
  • Operating unit and measuring unit can be separated The detachable measuring unit is convenient and useful for those samples requiring separation from operating unit.
  • Real time display of titration curve User can view the on-going titrations on display screen in real time.
  • Dispenser is now a standard equipment The reagent dispenser eliminates troublesome replacement of Karl Fischer reagent.
  • Measuring time is shortened by accelerated electrolysis (1.3 times faster than other models) Pre-titration and sample measurement time are now shortened 1.3 times faster by accelerated electrolysis.
  • GLP/GMP conformance Check results on the titration unit with standard substances are recorded, which are self-filed in a series for review, and the advance notice automatically appears on display to prompt periodic check and reagent replacement on schedule.
