Automatic Potentiometric Titrator

Large color TFT-LCD with a touch panel (8.4-inch) enables easy key entry.
Monitoring temperature during titration ensures safe measurements.



・Information stored in the electrode cable

The optional smart electrode cable with IC chip stores calibration results, replacement date etc. of an electrode. Time consuming recalibration can be avoided when multiple electrodes are used.

・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.

・Result output as PDF files

Paper saving and environmentally friendly – results no longer need to be printed. Measurement results are converted to PDF and can be stored in a USB flash drive.
