DSR-M Rotating Disc Ring ElectrodeThe main characteristics are:

DSR-M rotates the disk electrode, and its speed is displayed by LED. The speed can be adjusted through the knob below the LED, with a range of 50 to 10000 RPM.

The DSR-M rotating disk electrode panel also has a voltage signal output interface, which can be connected to an external voltmeter or data acquisition system to display changes in voltage signals. If necessary, the speed can also be adjusted using an external signal source through the interface on the panel. External signal sources can be sine waves, square waves, and other waveforms.

The external acceleration characteristics of the DSR-M rotating disk electrode system enable the rotational speed of the rotating disk electrode device to change synchronously with the external waveform. This feature is particularly suitable for applications in hydrodynamic regulation.

The DSR-M rotating disk electrode is easy to disassemble and has limited storage space. The host can be easily moved up and down and connected to the electrolytic cell for electrode immersion or removal experiments.

The DSR-M rotating disk electrode base is made of chemically resistant polypropylene material. It can be conveniently placed in a glove box for conducting research on non-aqueous systems.

DSR-M user test data:

1. The starting potential of DSR-M is basically the same as that of a certain SR, indicating that their responses are basically the same in the electrochemical starting stage

2. Half wave potential, DSR-M is higher, indicating that its measured performance is better than that of a certain SR

3. The maximum current density is basically the same, indicating that when dealing with currents of the same magnitude, the performance in terms of material transfer efficiency is similar, and the responses of the two are basically the same
