Rapid Measurement
Faster measurement is achieved by using a coarser thread which feeds the spindle by 2mm per revolution of the thimble instead of the standard 0.5mm. This increase in thread lead has been made possible thanks to new high precision thread-cutting and test techniques. Trials show that a reduction in positioning times of 60% and measuring times of 35%* can be obtained, compared with a conventional micrometer.
*According to Mitutoyo's comparison test data for measuring time on typical workpieces.

Comparison of Measuring Time on a Stepped Workpiece
The time needed to measure 6 diameters on a workpiece, from the smallest to the largest with the micrometer held in one hand, was recorded for a conventional digital micrometer and for the QuantuMike.

Repeatable Measurement
The patented ratchet thimble mechanism helps ensure repeatable results by transmitting microvibrations along the spindle to the contact face to provide a constant measuring force and encourage good contact with the workpiece. The ratchet works from the thimble as well as the speeder so it is always easy to use - even when making measurements one-handed. The sound of the ratchet provides the user with a sense of confidence and the speeder enables the rapid spindle feed needed when measuring widely different dimensions.

Features:

• Function lock helps prevent error
  • QuantuMike is equipped with a function lock feature to prevent the origin point being moved by mistake during measurement.
• Measurements are made to an accuracy of ±1µm/±.00005" throughout the range
• Graduated sleeve provides confidence check
  • A graduated scale is provided on the sleeve for use with a reference mark on the thimble so that every millimeter displacement can be checked to provide extra confidence
• Useful application of measured data
  • A statistical process control system and a measurement network system can be established to share quality information with a model equipped for data output
• Dust/water resistance with IP65 protection level
  • Excellent resistance against oil, water and dust enables this product to be used in machining situations that include splashing coolant fluid
