Description
Condition
Used (Very Good).
This digital micrometer presents very well overall, maintaining a clean and professional appearance. While there is some minor cosmetic spotting visible on the rotating body of the thimble and the moving spindle, this does not affect the mechanical operation or accuracy of the tool. The critical carbide measuring faces are clean, free of damage, and ready for immediate use. The item comes housed in its original plastic case and includes the adjustment spanner and the 100mm setting standard, which is still protected by its original wax coating. Please note that the original inspection papers are not included.
Product Overview
The Mitutoyo 293-250-10 is a high-accuracy “Coolant Proof” digital micrometer designed for measuring larger external dimensions in the 100mm to 125mm range. Rated to IP65, this instrument is protected against dust ingress and water jets, making it suitable for use in machining environments where coolant and cutting oils are present. It features Mitutoyo’s Ratchet Stop mechanism, which ensures a constant measuring force for consistent, repeatable results regardless of the operator. The digital LCD provides clear measurements with a resolution of 0.001mm, and the unit utilises the Absolute (ABS) linear scale to maintain the origin point, eliminating the need to re-zero after powering on.
