RRDE-9ARotating ring disk electrode device in conjunction with multiple electrochemical workstationsMain Features
1.Rotation speed isLEDDisplay, throughLEDThe knob below can adjust the speed, with a range of adjustment50to9500 RPMThe display error is0.1%.

2.There is also a voltage signal output interface on the rear board, which uses an external signal source to adjust the speed. External signal sources can be sine waves, square waves, and other waveforms.

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

4.The device 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.

5.The base adoptsGood corrosion resistance and oxidation resistanceof304Stainless steel material. It can be conveniently placed in a glove box for conducting research on non-aqueous systems.
