Introduction to Automatic Potentiometric Titimeter AT-710B

The automatic potentiometric titrator AT-710B is a common analytical instrument designed based on the principle of potentiometry for volumetric analysis. The principle of potentiometry is to select appropriate indicator and reference electrodes to form a working battery with the measured solution. With the addition of titrant, the concentration of the measured ion continuously changes due to chemical reactions, resulting in a change in the potential of the indicator electrode. Near the endpoint of titration, there is a sudden change in the concentration of the measured ion, causing a jump in electrode potential. Therefore, the endpoint of titration can be determined based on the jump in electrode potential.

The main features of the potentiometric titrator AT-710B are:

1. Compact and minimalist burette drive design, occupying only A4 size space.

2. Equipped with a 1/20000 high-resolution burette, bubbles are less likely to adhere to the tube wall.

3. Measurement results and methods can be stored on a USB flash drive to generate PDF files.

4. Use a computer to edit the measurement method and transfer the method to the host using a USB drive.

5. Built in one set of burettes, expandable to two sets without increasing space.

6. Connect a multi sample automatic sampler to perform fully automated measurement of multiple samples.

7. Connect the moisture analyzer and titrator through MCU-710 for simultaneous measurement.

8. Can connect intelligent electrode cables to record and store relevant information of electrodes.

9. Diversified interfaces provide users with functionality, scalability, and convenience.
