Speed rotation

Model 470, rpm measuring instrument set: Instrument with SoftCase (protective case) in transport case, incl. adapter, probe tip, surface speed disc, reflectors, batteries and calibration protocol

Model 470, the ideal combination of optical and mechanical rpm measurement. An optical measurement becomes a mechanical measurement by simply attaching an adapter for probe tip or surface speed disc.

  • Easy one-hand operation * Measurement of rpm, speeds and lengths
  • "Low Batt" warning
  • Robust design with SoftCase (protective case)
  • Storage of mean/max./min. values, last reading
  • Measurement distance up to 600 mm (optical measurement)
