164-164 Outside Micrometers

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

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

Flat Spindle Tip—Flat spindle tips are often used in measurement applications and for bearing against round surfaces.

Mitutoyo Electronic Micrometer Heads with Calibration Certificate

164 Model

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.
