10-100mm Digital Internal Groove Caliper With Preset, Stainless Hardened Metal Case, 3V Power - Metav IndustryLine

Taking advantage of a precise 0.01 mm digital readout, hardened stainless measuring faces and a dedicated design for internal grooves, this caliper delivers repeatable groove measurements within the 10–100 mm micro range; order the instrument directly via Metav Werkzeuge or request advice from our consultants for application support.

Digital internal-groove caliper M240.039.N — 0.01 mm resolution, preset, INOX (Metav IndustryLine)

The Digital internal-groove caliper M240.039.N is a compact, battery-powered instrument for accurate measurement of internal grooves and slots in small components across the 10–100 mm range

• 0.01 mm digital readout for fine precision
• Designed for internal groove measurement
• Hardened stainless measuring faces
• RB 5 data output for digital traceability

Accurate measurement in confined spaces

This instrument is built for precision where space is limited: with a measurement range of 10–100 mm it belongs to the micro class, making it suitable for fine mechanical and watchmaking tasks. The 0.01 mm resolution on the digital readout provides clear numeric feedback and reduces reading error compared to analogue scales. Because the instrument is explicitly configured for internal grooves, the measuring geometry and a 30 mm jaw length are optimised to reach narrow slots and recesses while maintaining stable contact. These characteristics translate into fewer re-measurements and a smoother inspection workflow.

Robust construction for consistent results

A combination of stainless steel components, hardened measuring faces and a metal housing ensures the caliper withstands everyday workshop handling without losing accuracy. The instrument’s mass (approx. 0.44 kg) and rigid construction reduce susceptibility to twist during measurement, improving repeatability when taking internal groove readings. Built to a reliable workshop standard, the solid materials also reduce long-term wear at the contact surfaces, which preserves calibration and extends service intervals.

Digital workflow and traceability

Equipped with a preset function and a straightforward display featuring ON/OFF and zero/preset controls, the caliper supports fast set-up and comparative work. Power is supplied by a 3 V cell for dependable operation, and the integrated RB 5 data output provides a direct channel for transferring measured values into digital records or quality-control software. The combination of immediate numeric output and data transfer capability reduces transcription errors and facilitates traceability in production or inspection records.

Where this caliper delivers most value

The instrument excels in precision trades and component inspection where internal grooves, slots and small recesses are critical features. Typical applications include micromechanical assemblies, small mould components and fine finishing operations in which accurate groove depth or width is essential. Thanks to its focused geometry and digital interface, the caliper integrates well into small-series production lines or laboratory benches where consistent, documented measurements are required.
