Digital Micrometer

Digital Outside Micrometer — 0–25 mm

The Digital Outside Micrometer (0–25 mm) is a precision measuring instrument used for accurate external diameter and thickness measurement of small components, test specimens, paper, thin materials, and gauge blocks to a resolution of 0.001 mm (1 μm). The digital display eliminates parallax and thimble-reading errors, providing fast and traceable dimensional verification in civil engineering testing labs, calibration labs, and production QC.

JS Civil Lab Solutions supplies stainless steel digital micrometers with NABL-traceable calibration for civil, mechanical, and paper/pulp testing laboratories.
