RP-732
For line speed measurement
  • Direct readout of line speed in combination with the TM-3100 series digital tachometers.
  • Available to detect speed nearby 0 r/min.
For distance measurement
  • Backlash can be adjusted automatically when stopped, with reversible counting function (available in combination of RP-732 with a reversible counter, excluding RP-721).
