• Up to four independent titration stations can run at the same time!
  • Comprehensive data handling!
  • Compact design!
  • New patented technologies!
  • GLP compliant functions!

Large sized color graphics LCD displays real-time
titration curves and differential curves to show reaction
tendencies, etc. All information is easily viewed.

Titration with a small amount of sample is possible thus reducing analysis costs and waste. (Optional)

Measurement with 1/2 of the sample volume is possible by using sample vessels and electrode holders that are designed for small amounts of samples. The reagent amount to be used and the waste solution volume after measurement can be greatly reduced, thus saving time and money.

GLP correspondent functions to support reliability of the titration results are provided.

For instance, buret precision tests and electrode calibration slope measurements add to the reliability of the titration results. Useful functions for maintenance such as electrode information display, reagent remaining volume indication etc. are also provided.

Data storing function to USB JumpDrive is provided. Large numbers of data points may be archived.

The titration results and titration conditions including titration/ differential curve data can be stored on a USB JumpDrive to perform recalculation and redetection.* Reading, recalculation and redetection of titration results, and use of data by
using other application software is possible by simply downloading the data to a laptop or PC for storage or processing.
To edit and view the data stored in USB, an optional software "Titra-Net Viewer" is necessary. The PC-controllable type, COM-1750, is provided with this software CD.

This titrator may be used as an automatic titration station for multitasking applications.

Different titrations can run in parallel at the same time!

Up to four titration stations are available on both the base stand-alone unit and the PC-controlled unit.
