Product Specification

Metrology External Micrometer

0–25mm Analogue External Micrometer (DIN 863)

Precision Carbide-Tipped Measurement Tool

Precision Measurement Engineering

This analogue external micrometer is designed for high-accuracy length measurement. Built according to DIN 863 standards, it features precision lapped, carbide-tipped measuring faces to ensure durability and minimal wear. The tool includes a hardened and ground spindle, a non-reflecting chrome-plated barrel with clear black engravings, and a combined sensitive ratchet, enabling both one-handed use and operation within restricted spaces.

Key Technical Highlights

  • Accuracy: 0.01 mm scale divisions.
  • Protection: Includes hand temperature insulation.
  • Operation: Sensitive ratchet for consistent measuring force.
  • Durability: Carbide-tipped faces and hardened spindle.

Understanding Micrometer Measurement

To ensure consistent and accurate readings, the micrometer utilizes a sensitive ratchet mechanism. This ensures that the same measuring force is applied every time, preventing the spindle from over-tightening against the workpiece. Hand temperature protection is integrated into the frame to minimize thermal expansion errors during long measurement sessions.

Available Calibration & Marking Services

  • Standard Calibration (25mm): 012050 25, 022000 25
  • DAkkS Calibration (100mm range): 012060 100, 022010 100
  • Identification: Laser-etched labelling (018940)
