Metav IndustryLine Digital Three‑Point Internal Micrometer, 75–88 mm – IP65, carbide faces

The Metav IndustryLine digital three‑point internal micrometer offers a compact, workshop‑rated solution for precise internal diameter measurement, especially where blind‑hole checking and repeatable contact are required.

• IP65 protection for harsh environments
• Carbide measuring faces for wear resistance
• Resolution 0.001 mm digital readout
• Suitable for blind‑hole measurements

Confidence where tolerance matters

The instrument delivers high repeatability with an indicated accuracy of ±0.005 mm, supported by a display resolution of 0.001 mm. Its three‑point measuring head ensures stable contact around the bore, which reduces eccentricity errors common with single‑point probes; this is particularly beneficial when inspecting small bores or stepped internal diameters. The device conforms to DIN 863 measurement principles and is classified for the micro measurement range (up to 100 mm), making it well suited for precise checks in toolmaking, gauge workshops and quality control stations where consistent, verifiable results are required.

Built for the workshop and production floor

Designed to withstand routine industrial use, the micrometer features IP65 protection and carbide measuring faces, which together extend service life and reduce downtime from cleaning or wear. The ingress rating protects electronics and mechanics from coolant spray and fine dust, enabling measurement close to the machine centre without compromising accuracy. A robust construction and clear digital display minimise handling errors, so process control becomes more efficient and inspection throughput improves without sacrificing traceability.

Fast setup and traceable output

Practical features reduce setup time and support data collection: the unit is supplied with a setting ring and an extension, facilitating rapid calibration to reference diameters and access to deeper bores. The digital display includes ON/PRESET, mm/inch and HOLD functions for flexible use across inspection routines, while the RB 6 data output allows integration with data loggers or inspection software for downstream documentation. These features combine to speed routine checks and feed reliable measurement data into quality systems, helping standardise inspection across shifts and operators.
