Inside‑Groove Vernier Caliper M201.137 — 30–250 mm range, 0.05 mm vernier

The Inside‑Groove Vernier Caliper M201.137 is an analogue precision caliper designed to measure internal grooves and narrow slots in metalworking, toolmaking and assembly tasks.

• 30–250 mm measuring range
• 0.05 mm vernier resolution
• Matt chrome, INOX stainless finish
• Locking screw for secure readings

Dependable precision for routine inspection tasks

The Inside‑Groove Vernier Caliper M201.137 combines a practical measuring span with a fine vernier scale for clear, reproducible readings. The 30–250 mm span places the tool in the standard caliper class, offering the best balance between reach and rigidity for general mechanical and metalworking tasks. The vernier 0.05 mm graduation provides workshop‑grade resolution while the stated accuracy 0.15 mm reflects the instrument’s role as a robust checking tool rather than a metrology‑lab instrument. As an analogue vernier, it requires no power source and is immediately ready at the bench, which minimises downtime in routine quality checks and set‑up inspections.

Robust materials and ergonomic handling for repeatable results

Constructed from INOX (stainless steel) with a matt chrome finish, the frame and jaws resist corrosion and retain a consistent slide action under regular shop conditions. The caliper is fitted with an integral locking screw to secure the slider during measurement transfer and to reduce reading error caused by transient movement. The measuring jaws feature an 80 mm effective length suited to reach into groove profiles while remaining stiff enough to avoid twist under normal hand pressure. These material and design choices support repeatable measurements and a long service life in production environments.

Practical application in production and workshop workflows

This inside‑groove caliper is particularly useful for checking groove widths, seat depths and narrow slot dimensions during assembly, small‑batch machining and first‑article inspections. Its analogue nature makes it straightforward to interpret on the shop floor: the 0.05 mm scale allows quick conformity checks and the simple construction reduces the need for frequent recalibration. The tool integrates well with standard quality control routines where rapid verification and clear pass/fail decisions speed up throughput. For traceable metrology requirements, the caliper serves as a robust reference instrument within a broader inspection process.
