Mitutoyo’s QuantuMike line of micrometers feature improved measurement time, repeatability and accuracy as well as ergonomics. The micrometer provides accuracy at ±1 µm /0.00005” throughout its measuring range and is also water and dust resistant.
A coarser thread feeds the spindle at 2 mm per thimble-revolution instead of the standard 0.5 mm.
The micrometer’s measurement repeatability is enhanced by a patented ratchet thimble drive mechanism that transmits induced micro-vibrations to the spindle contact face, providing a force that encourages good workpiece contact. Ergonomic design enables the ratchet to be worked from either the speeder or the thimble, easing one-handed measurements.
The micrometer also features additional confidence-building features, such as a function lock, that prevents the digital display-indicated origin point from being mistakenly moved during measurement. A graduated scale on the sleeve coordinates with a reference mark on the thimble confirming each millimeter displacement.
