Karl Fischer Moisture Titrator (Volumetric titration)

High-performance titrator at a lower price



・New burette unit

The new burette unit has the switching valve mounted directly on top of the
cylinder. Less dead space between the switching valve and the cylinder and it
inside of the cylinder left less residual titrant when replacing it.

・No need to adjust settings for different types of solvent and samples

Our proprietary technology (endpoint detection by compensating liquid resistance, Japanese Patent No.1896338) makes it unnecessary to change the detection electrode sensitivity and the endpoint voltage depending on the nature of each solvent and sample.
This feature reliably prevents over titration and ensures highly accurate measurements.

・Easy injection/drain of dehydrated solvent

The stirrer unit is equipped with a pump for injecting/
draining dehydrated solvent.
Once you set the operating time of the pump with the internal timer, the optimum quantity of the solvent is automatically injected.

  • New burette unit
  • Measurement results are converted to PDF and can be stored in a USB flash drive
  • End point detection by compensating liquid resistance is adopted. (Japanese Patent No. 1896338)
  • Can resume titration automatically after interruption
  • By connecting an Android device , a titration curve can be displayed in real-time
