Spi CMS220519035 Interchangeable Anvil Micrometer 6-12 in

Product Description

The SPI CMS220519035 is an electronic interchangeable anvil micrometer designed for precise outside diameter and large-workpiece measurements across a 6 to 12 inch range using a set of six included anvils. The unit delivers plus or minus 0.0003 inch accuracy with a ratchet stop thimble for consistent measuring force and a rotating spindle for ease of use. A positive lock nut holds readings in place, and a digital counter with data output port supports integration into statistical process control workflows. A licensed metrology technician or precision machinist is the typical end user.

This micrometer is suited for inspection and quality control work on large-diameter shafts, bores, and machined components in manufacturing, toolroom, and metrology lab environments. The six interchangeable solid carbide anvils allow the single instrument to cover the full 6 to 12 inch span without changing tools, reducing setup time when checking a range of part sizes. The unit ships factory calibrated and meets ASME B89.1.13 standards, making it appropriate for environments that require documented measurement traceability.

Compatibility

Designed as an OEM-style precision measuring instrument for use in toolroom, inspection, and quality control applications requiring outside micrometer measurements in the 6 to 12 inch range.

Installation Notes

Select and seat the correct anvil for the measurement range before use, and verify calibration against a known standard prior to inspection work. Store the instrument in the included wood box when not in use to protect the measuring faces from contamination and damage. No power tools or installation hardware are required; handle the carbide anvil faces carefully to avoid chipping.
