Frequently Asked Questions

Universal digital micrometers are designed with interchangeable anvils, such as flat, spherical, spline, disk, and blade types. This adaptability allows a single instrument to perform a wide variety of tasks from measuring the thickness of flat parts to reaching into narrow grooves or checking the wall thickness of curved pipes.

The integrated LCD screen provides high-resolution readouts (typically to 0.001mm or 0.00005"), which eliminates the interpretation errors common with traditional vernier scales. Functions like "Origin-Set" and "Zero/ABS" allow technicians to quickly switch between absolute measurements and incremental comparisons, streamlining complex inspection workflows.

Many universal models, such as the Mitutoyo 339 series, utilize a non-rotating spindle design. This ensures that the interchangeable anvils move linearly against the workpiece without any twisting motion, preventing surface scuffing on delicate parts and ensuring that the measurement is perfectly perpendicular.

Yes, the instruments in this collection often feature IP65-rated protection. This ensures that 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.

Most high-end digital universal micrometers include a data output port. This allows the tool to be connected to a computer or SPC (Statistical Process Control) system via a cable or wireless transmitter, enabling the automatic logging of measurements for compliance and detailed audit trails.

HK Calibrations provides professional calibration services traceable to national standards. Because these tools use multiple interchangeable anvils, regular professional verification is essential to ensure that every combination remains perfectly aligned, flat, and accurate throughout its service life.
