Mechanical & Digital Micrometer Calibration

Precision micrometer calibration up to 48″ β€” outside, inside, depth, and digital models per ASME B89.1.13

Dimensional Calibration

Outside, Inside & Depth β€” Up to 48" | Resolution to 0.00005"

Mechanical & Digital Micrometer Calibration

At E&S Tool & Calibration Services, we provide precise, accredited calibration for mechanical and digital micrometers of all types and ranges up to 48 inches. Whether used in machining, inspection, or quality control, micrometers are fundamental tools β€” and their accuracy directly impacts product conformity and dimensional integrity.

We calibrate both standard analog and digital micrometers, verifying their performance to meet or exceed industry standards such as ASME B89.1.13. From 0–1" bench micrometers to extended-range inside and depth micrometers, E&S provides reliable, high-quality calibration backed by precision equipment and expert attention to detail.

Micrometers We Calibrate

Complete coverage for all micrometer types, configurations, and accessories

Outside Micrometers

Standard frame, digital, ratchet stop, friction thimble, and non-rotating spindle types β€” calibrated across the full measurement range per ASME B89.1.13.

Inside Micrometers

Rod-type and tubular sets in mechanical and digital formats β€” calibrated for accurate bore and internal dimension measurement across extended ranges.

Depth Micrometers

Flat-base and interchangeable rod-type depth micrometers in analog and digital formats β€” calibrated for accurate slot, step, and recess depth measurement.

Digital Micrometers

Electronic micrometers with absolute encoders, data output, and resolution down to 0.00005" β€” calibrated with verification of display accuracy and electronic function.

Setting Standards & Extension Rods

Micrometer setting standards and extension rods up to 48" β€” calibrated to verify the accuracy of reference standards used with multi-range micrometer sets.

Interchangeable Anvils & Accessories

Interchangeable anvils, spacers, and accessories for multi-range micrometers β€” calibrated to ensure the complete measurement system maintains accuracy.

Calibration Services Include

Comprehensive verification of accuracy, mechanical function, and measurement integrity

  • Multi-point verification across the tool's full measurement range using certified gage blocks, end standards, or a supermicrometer
  • Testing for zero setting, repeatability, spindle movement, and return-to-zero accuracy
  • Functional checks of ratchet or friction thimble, lock mechanisms, and digital display functionality for electronic models
  • As-found and as-left data with clear documentation of any deviation from nominal at each test point
  • Calibration certificates traceable to NIST and compliant with ISO/IEC 17025 and ASME B89.1.13
  • Detection of spindle backlash, wear, or electronic drift that could compromise measurement results

Why Calibrate Micrometers?

Micrometer accuracy directly impacts product quality and dimensional conformance

Tight-Tolerance Accuracy

Ensures accuracy in tight-tolerance applications and production measurement β€” where even small deviations can cause parts to fall outside specification.

Detect Wear & Backlash

Detects spindle backlash, electronic drift, and wear that can compromise results β€” catching problems before they cause costly scrap or rework.

Industry Standard Compliance

Maintains compliance with ISO, aerospace, defense, and machining industry standards β€” providing traceable documentation for your quality management system.

Standards & Compliance

All micrometer calibrations performed in accordance with applicable standards

NIST Traceable ISO/IEC 17025 ASME B89.1.13 ISO 9001 ANSI/NCSL Z540
