Mitutoyo Digital Micrometer 0-25mm No. 293-421-20

Description

The Mitutoyo Digital Micrometer, Model No. 293-421-20, is a digital outside micrometer with a 0-25 mm measuring range and 0.001 mm resolution. It features a clear LCD display (showing 0.764 mm in the image) for precise readings, designed for external measurements in machining and engineering tasks. The carbide-tipped measuring faces ensure durability, with a flatness of 0.3 µm and parallelism within 1 µm, meeting Mitutoyo’s high standards.

Accuracy is ±1 µm, and the measuring force ranges from 5-10 N. The 6.35 mm diameter spindle has a 0.5 mm pitch, with a spindle lock for consistent readings. It includes a ratchet stop for repeatable measurements and functions like origin-set, zero-set, and auto power-off after 20 minutes of inactivity. The micrometer is powered by an SR44 battery, with a typical life of 2.4 years under normal use.

This unit is in excellent condition, showing minimal signs of use, and comes in its original plastic case with an inspection certificate. Made by Mitutoyo, this micrometer is a reliable choice for machinists needing precise measurements in the 0-25 mm range. No additional accessories, such as a setting standard or spanner, are included beyond the case and certificate.
