Main characteristics of DSR-M

The speed of DSR-M rotator is displayed by LED, which can be adjusted through the knob below the LED, with a range of 50 to 10000 RPM.

There is a voltage signal output interface on the back panel of the DSR-M rotator, which can be connected to an external voltmeter or data acquisition system to display changes in voltage signals. The speed can also be adjusted using an external signal source through the interface on the panel if needed. External signal sources can be sine waves, square waves, and other waveforms.

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

The DSR-Mrotator is easy to install and remove, and takes up little space. it can be easily moved up and down and connected to the cell for electrode immersion or removal experiments.

The support frame of the DSR-M rotator is fabricated from chemically resistant polypropylene material. It can be placed in a glove box conveniently for conducting research on non-aqueous systems.

Test data from customers
