These micrometer heads come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. For easier reading than other micrometer heads, these show measurements on an LCD. Mount them in jigs, fixtures, machine tools, movable tables, and other equipment that require precise adjustments. They are held in place by the cylindrical mounting hub using your existing brackets or fixtures. Spindle length is the maximum extended distance when the micrometer head is set at zero.

Zero-position memory, also known as absolute (ABS) positioning, retains the measuring position when the micrometer is turned off. A zero-set button lets you start measuring at any point. SPC data output allows for connection to a computer or data processor.

Plain thimbles turn freely without friction or a stopping device and rely on operator feel for accurate measurements.

Ratchet-stop thimbles have a constant-force mechanism to ensure repeatable measurements without relying on operator feel. They also have a speeder knob to reduce the time it takes to move the spindle. Once the spindle contacts the surface of the measured object, it will stop tightening, but the speeder knob will continue turning with a clicking sound.

Nonrotating spindles prevent scratches on delicate work surfaces and eliminate distortion of soft or elastic material.

Flat spindle tips are often used in measurement applications and for bearing against round surfaces. Round spindle tips minimize errors from misalignment, so they’re often used as feed devices.

Clamp nuts securely hold the micrometer head and provide extra support.

USB data cable (sold separately) connects the micrometer head directly to your PC.

10-pin data cables (sold separately) connect the micrometer to a Mitutoyo miniprocessor or multiplexer.

Wireless data transmitter and receiver (sold separately) allow you to transmit measurement data from to your PC without being tethered by a cable.
