Product details
It is used to measure rotational speeds with or without contact. The non-contact measurement of the rotational speed is done using reflective tape that is applied to the object being measured. For contact measurement, the user can choose to measure either the revolutions per minute or the surface speed. The measurement values can be stored. By pressing and holding the save button during measurement, the device saves the last, maximum, and minimum values of the period when released. These can then be retrieved immediately after the measurement.
