Four-Channel Automatic Potentiometric Titrator AT-710M

Potentiometric Titration Method: Place the beaker containing the test sample solution on the electromagnetic stirrer, immerse the electrode, stir, and add the titrant stepwise from the burette. Initially, larger amounts may be added each time while stirring and recording the potential. As the endpoint approaches, small increments should be added, stirring and recording the potential each time. Continue adding the titrant a few more times after the jump point and record the potential.

Main Features of the Four-Channel Automatic Potentiometric Titrator AT-710M:

1. Equipped with a large 8.4-inch color LCD touch screen for operation and control.
2. Simultaneously controls four automatic potentiometric titrators and Karl Fischer moisture analyzers.
3. Intelligent burette unit with titration reagent information stored in the chip.
4. Smart electrode cable that records and stores electrode-related information.
5. New burette unit design reduces dead volume and reagent consumption.
6. Wireless Bluetooth operation via touch screen for enhanced safety and reduced risk.
7. User permission settings to prevent incorrect configurations 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, with PDF experiment reports generated.
