Inside micrometer by Microtech Metrology — Digital, 125–4000 mm range, ISO 17025

The inside micrometer is a modular digital bore measuring system designed for long‑span internal measurements in production and inspection environments, combining a fine 0.001 mm readout with industrial IP65 protection

• Digital display with ON/ABS, SET, HOLD, mm/inch
• ISO 17025 calibration with certificate included
• Ratchet stop for consistent measuring force
• Modular 125–4000 mm measuring range with extensions

Traceable accuracy for critical inspection tasks

Designed for repeatable results, this measuring system delivers an official ISO 17025 calibration certificate on delivery, ensuring measurement data are traceable and auditable. The instrument’s stated accuracy ±0.05 mm is supported by a 0.001 mm display resolution, which allows clear reading of fine increments and reduces interpretation errors. For quality assurance workflows and incoming inspection, the certified status removes uncertainty about conformity and simplifies documentation in regulated production chains.

Built for demanding shop‑floor conditions

With an IP65 rating and a sealed electronic module, the unit tolerates dust and water jets that are commonly encountered in metalworking environments. The incorporated ratchet stop provides a consistent measuring force, which mitigates operator‑induced variance during repeated internal measurements. These features combine to reduce rework and inspection time, improving throughput without compromising reliability.

Flexible measurement span that grows with production

The modular concept supplies a comprehensive set of extensions (25 + 50 (2 pcs) + 100 (2 pcs) + 200 (2 pcs) + 400 (8 pcs)), allowing coverage from 125–4000 mm with a compact base instrument. This approach keeps initial investment focused while offering scalable reach for larger components such as housings, bearings and shafts. Modular assembly is rapid and secure, so long‑length checking can be performed with minimal setup overhead.

Clear operation and efficient data capture

The digital display includes ON/ABS, SET and HOLD functions plus a selectable mm/inch mode to match documentation standards. Readings appear instantly on the high‑resolution screen, and the ergonomics of the measuring head—including a 22 mm component diameter for stable support—help maintain alignment in bore gauging. Together these elements shorten measurement cycles and make the tool a pragmatic choice for shop and laboratory use.
