Automatic Potentiometric Titrator AT-710S

The automatic potentiometric titrator is an analytical instrument designed based on the principle of potentiometric titration and is used for volumetric analysis.
The principle of potentiometric titration is: select an appropriate indicator electrode and reference electrode to form a working cell with the test solution. As the titrant is added, the concentration of the measured ion continuously changes due to chemical reactions, causing the potential of the indicator electrode to change accordingly. Near the titration endpoint, the concentration of the measured ion changes abruptly, resulting in a sharp jump in the electrode potential. Therefore, the titration endpoint can be determined based on this abrupt change in electrode potential.

Main Features of Automatic Potentiometric Titrator AT-710S:

1. Equipped with a large 8.4-inch color LCD touch screen for operation and control.
2. Intelligent burette unit with titrant information stored in the chip.
3. Smart electrode cable that records and stores electrode-related information.
4. New burette unit design reduces dead volume and reagent consumption.
5. Touch screen and main unit feature a split design and can display simultaneously.
6. The measurement unit can be placed inside a fume hood for enhanced safety and reduced risk.
7. User permission settings function to prevent incorrect settings and facilitate management.
8. Simultaneously records two different detection electrodes, such as pH and photometric.
9. Measurement results can be stored on a USB drive, and PDF experiment reports can be generated.
