Three‑point inside micrometer M312.267 — digital internal micrometer, 325–350 mm, Metav IndustryLine

The Three‑point inside micrometer M312.267 is a digital instrument designed for accurate internal measurements in machine shops and quality inspection, ideal where medium‑range bore and ring accuracy is required.

• Digital display with mm/inch and ABS functions
• Measuring range 325–350 mm for medium assemblies
• Carbide measuring faces for wear resistance
• Supplied in a transport case

Consistent medium‑range precision for production control

This instrument covers the 325–350 mm interval and is classified in the medium range for internal measurement, making it well suited to fixture work, housing bores and rotary components where reach and stiffness must be balanced. The specified accuracy of ±0.012 mm supports reliable control tolerances during serial inspection and set‑up tasks. The spindle and three‑point measuring geometry provide repeatable contact with the bore, reducing operator‑induced variation and enabling faster decision cycles on the shop floor. As a consequence, throughput and first‑pass yield improve when this measuring principle replaces slower or less rigid methods.

Clear digital handling and secure data transfer for traceability

Equipped with a digital display featuring ON/0‑, mm/inch, ABS, PRESET and HOLD functions, the instrument offers immediate readback and basic data handling without added peripherals. For process integration the unit includes RB 4 data output, which permits connection to data collection devices or quality management systems and reduces transcription errors. Operators benefit from faster measurement routines and straightforward switching between metric and imperial units, while production engineers gain an auditable measurement stream that simplifies SPC sampling and corrective actions.

Durable construction and transport protection for workshop use

Built for daily shop use, the micrometer has carbide measuring faces that maintain form and surface finish under repetitive contact. A measuring depth of 140 mm and a stable mechanical frame with a weight of 5 kg deliver the stiffness required for reproducible readings across the full span. Delivery in a protective case ensures safe transport between inspection benches or job sites; note that the scope of delivery explicitly excludes a setting ring. This combination of wear‑resistant contacts and protected storage reduces downtime and maintenance efforts over the instrument’s service life.

Practical fit for machine shops and inspection benches

Metav IndustryLine positions this instrument as a workshop‑grade solution for routine internal measurement tasks where medium reach and dependable accuracy are required. The three‑point concept is particularly effective for measuring stepped bores and internal diameters with limited access. The instrument supports straightforward workflows in small series production as well as in maintenance and overhaul applications, contributing to consistent quality outputs from the inspection stage through to final assembly.
