VEER make Slip-Speed Meter VSS-01 is portable instrument which is very useful to find RPM, Corrected RPM, %Slip and Frequency of electric Motor. It is very simple and easy to use Instrument so, any one can operate it easily.

Theory of Operation

It measures signal from slip coil which is very weak slip signals. It amplifies it and then calculates RPM and %Slip and also calculates corrected RPM @ 50 Hz (60Hz on request). It also measures Line Frequency.


  • To measure RPM and %slip of submersible pumps at Line Frequency.
  • It can also be used in lab as well as in motor industry for Rotational Speed measurement (Optional)
