Designed for measuring inner diameters of Wertc parts by the comparison method. This series uses a precision guide protection bridge that self-centers, delivering accurate and repeatable readings. The measuring head has an active probe on one end and a replaceable probe on the other, allowing quick adaptation to the aperture to be measured. Weight: 1.72 kg. Benefits - Accurate, repeatable inner-diameter measurements with minimal setup - Self-centering guide protection bridge reduces misalignment and improves reliability - Replaceable probe end enables coverage of different bore sizes by swapping tips - Robust, stable design suitable for shop floor QC, tooling setup, and maintenance Use scenarios - On the production line, verify Wertc part bore sizes during quality control checks - During tool and jig setup, confirm bore tolerances to ensure proper fit - In maintenance, inspect Wertc assemblies for wear or out-of-tolerance bores
