Equipped such as high-speed & high-precision measurement by "Hybrid titration method" which uses both "Volumetric titration method" and "Coulometric titration method", and "Electrolytic Factor Measurement System" which does not require pure water for factor determination. "Hybrid titration method" automatically switches between the parallel measurement by "Volumetric titration method" and "Coulometric titration method" by monitoring moisture content in titration cell with high-speed & high-precision measurement, therefore can measure without adjusting the sample amount. With just pressing one button, the "Electrolytic Factor Measurement System" automatically performs the factor determination of Karl Fischer reagent, and save the time & work without using pure water. To make the inner burette and diaphragm separate, although after measuring such as petroleum samples, it is easy to clean the diaphragm inner burette. It is possible to select one method from "Volumetric titration method", "Coulometric titration method", and "Hybrid titration method". It is possible to store the measurement result, method and manage the data as an electronic record.
