*Digital readout with mm/inch and hold function
*Carbide measuring faces for wear resistance
*Designed for blind‑hole measurement, 50–63 mm range

High precision where it matters most

This instrument delivers accuracy ±0.005 mm with a fine resolution 0.001 mm, offering repeatable results for small to medium bores. The three‑point contact geometry centres automatically inside the bore, reducing alignment errors and minimising the need for setup time. For metrology tasks that demand micrometre‑level control, this measuring device provides a reliable balance of sensitivity and robustness that supports consistent in‑process inspections and final control checks.

Clear digital operation for faster workflows

A well‑laid‑out digital readout with ON/OFF, SET, HOLD and mm/inch functions simplifies data capture and reduces interpretation errors on the shop floor. The display logic and simple keys speed up routine measurements and make cross‑checks straightforward, while the device’s RB6 data‑interface identification supports downstream recording and traceability. Measured values are easier to document, helping to shorten inspection cycles and improve throughput in serial production.

Built to withstand regular workshop use

The measuring anvils feature carbide measuring faces, chosen for their abrasion resistance and long service life under frequent contact. The construction tolerates routine handling in production environments and maintains stable measuring performance across repeated cycles. Supplied without setting ring or extension, the instrument is optimised for direct use within its 50–63 mm measuring range and is particularly suited to blind‑hole bores where three‑point contact ensures a centred measurement.

Fits into quality systems and calibration routines

With an industrially relevant accuracy of 0.005 mm, the micrometer integrates well into standard quality assurance processes. The compact dimensions and precision make it suitable for laboratory spot checks as well as assembly‑line quality control. The instrument’s characteristics support documented measurement procedures and help to fulfil internal inspection plans; its technical specification complements traceable workflows and reduces uncertainty in acceptance decisions.
