Internal Precision Gauge «Innen‑Feinmessgerät» – analogue, carbide contact faces, 250–450 mm range by Microtech Metrology

Internal Precision Gauge «Innen‑Feinmessgerät» is a workshop-grade device for reliable internal diameter measurement in medium-sized components, designed as an analogue fine measuring instrument for machine shops and quality control

• Carbide measuring faces for long life and low wear
• Analog vernier with 0.01 mm graduation
• Measuring range 250–450 mm
• 2000 mm measuring depth for deep bores

Accuracy and repeatability that support quality control

The instrument offers an accuracy of ±0.022 mm and an analogue vernier readout with a 0.01 mm graduation, making it suitable for tasks where traceable, repeatable results are essential. The mechanical design reduces susceptibility to electromagnetic interference and battery failures, while the fine graduation supports tight tolerance checks without the complexity of digital electronics. Such characteristics translate into fewer measurement cycles and clearer go/no‑go decisions on the shop floor, improving throughput and lowering scrap rates.

Reach into deep bores and large housings

With a measuring range of 250–450 mm and an exceptional measuring depth of 2000 mm, this fine instrument is aimed at medium-class measurement requirements where access is deep or components have recessed bores. Classified in the medium range (300–500 mm), it balances reach and stiffness: sufficiently long to inspect sizable internal diameters, yet rigid enough to keep alignment errors and bending-induced deviations to a minimum. This makes it a practical choice for fixture, housing and clutch‑component inspection.

Durable contact faces for consistent results

The device is fitted with carbide measuring faces, providing significantly improved wear resistance versus standard steel tips and maintaining measurement integrity over prolonged use. Carbide contacts reduce surface damage to measured parts while preserving the contact geometry that underpins reliable repeatability. For workshops performing frequent inspection runs or handling abrasive materials, this robustness means less frequent recalibration of the contact surfaces and steadier tolerance control between service intervals.

Practical benefits for production and inspection workflows

As an analogue fine measuring instrument, it is straightforward to operate, requires no batteries and integrates easily into established inspection routines. The design supports common internal measurement operations in mechanical engineering and metalworking, such as bore verification, counterbore checks and production spot‑checks. Combined with Metav’s supply chain and quality filter in Emmerich, the instrument arrives as a pragmatic step towards reproducible measurement data across small and medium production runs, helping teams to deliver consistent parts and reduce downstream quality incidents.
