Three‑point internal micrometer M836.720 — self‑centring, 125–150 mm range, analogue

The Three‑point internal micrometer M836.720 is an analogue, self‑centring measuring instrument designed for precise internal diameter inspection in workshop and production metrology.

• Self‑centring three‑point measuring system
• Measurement range 125–150 mm
• Accuracy 0.008 mm · Resolution 0.005 mm

Consistent centring for repeatable bore measurement

The three‑point contact geometry provides a uniform seat against bore surfaces, which reduces eccentricity and substantially improves repeatability compared with single‑point probes. Combined with an analogue spindle and fine graduation, the instrument achieves an accuracy of 0.008 mm and a resolution of 0.005 mm, making it suitable where sub‑hundredth millimetre consistency is required. This design shortens setup times on repetitive checks and produces stable readings even in blind or recessed bores.

Purposeful dimensions for everyday shop use

With a measurement span of 125–150 mm, the micrometer falls into the Standard (100–300 mm) class: a pragmatic compromise between reach and stiffness that fits most machining and assembly tasks. The instrument’s self‑centring action and three‑point kinematics are especially advantageous when measuring bearings, housings or bore features where quick alignment and reproducible seating matter. The mechanical construction favours robust handling in a production environment and resists small impacts better than delicate electronic heads.

Straightforward handling and dependable inspection results

The analogue readout keeps the concept simple: the finely graduated spindle permits controlled approach to the workpiece, and the three‑point framework locks the measuring head concentrically in the bore. Measuring faces are integrated into the contact system to provide defined contact geometry and reliable tactile feedback while measuring. Routine checks are therefore faster, with fewer adjustment cycles, and the instrument delivers consistent assessment of incoming parts or in‑process features — supporting clear pass/fail decisions on the shop floor while preserving traceable quality control practices.

FAQ

What is the measuring range of the instrument?
The Three‑point internal micrometer M836.720 (Metav IndustryLine) covers a measurement span of 125–150 mm.

What accuracy and resolution can be expected?
The instrument specifies an accuracy of 0.008 mm and a readable resolution of 0.005 mm, using an analogue spindle and fine graduation.

How does the self‑centring three‑point system improve measurements?
The three contact points centre the head automatically within the bore, reducing eccentricity and producing more repeatable diameter readings than single‑point contacts.

For which applications is this micrometer best suited?
It is intended for internal diameter inspection of bearings, housings, bores and similar components in workshop and production quality control where a Standard‑range instrument is appropriate.

Is calibration information provided for this item?
