Frequently Asked Questions

Outside digital disc micrometers feature large, circular measuring faces that are specifically designed to fit into narrow spaces, such as between gear teeth. This unique geometry allows technicians to measure the "root tangent length" of spur and helical gears, providing a level of access that standard flat-tipped micrometers cannot achieve.

The integrated LCD screen provides an instant, high-resolution readout (typically to 0.001mm), which eliminates the risk of parallax or interpretation errors common with manual scales. Features like "Origin-Set" and "Zero/ABS" allow for quick switching between absolute and incremental measurements, streamlining complex inspection tasks.

Yes, the wide, flat surface of the discs makes them ideal for measuring the thickness of soft or deformable materials, such as paper, felt, rubber, and plastic. The increased surface area of the disc spreads the measuring force, preventing the spindle from "sinking" into the material and ensuring a more accurate thickness reading.

Models like the Mitutoyo 369 series often incorporate a non-rotating spindle design. This ensures that the disc face moves linearly against the workpiece without any twisting motion, preventing scuffing on delicate surfaces and ensuring that the measurement is perfectly perpendicular to the part.

Many instruments in this collection feature IP65-rated protection. This ensures the sensitive electronic components are sealed against the ingress of water, oil, dust, and coolants, allowing the micrometer to maintain its precision even when used directly at the machine tool during production.

HK Calibrations provides professional calibration services that specifically verify the flatness and parallelism of the oversized disc faces. Because these faces are larger than standard tips, regular professional testing is essential to ensure they remain perfectly aligned and traceable to national standards.
