Overview
A balanced dial face reads movement either side of zero, which makes this Mitutoyo indicator suited to comparing a surface against a reference point. The flat back mounts by a clamp on the stem or a plate on the rear.
Fine graduation makes it useful for tolerance checks. The description mixes in options such as black dials and lug backs that this model does not use.
Who it's for
Inspectors and machinists reading in inches who prefer a flat back. Users who want a lug back or a metric scale should confirm the model carefully.
Pros and cons
- Very fine graduation
- Balanced dial for comparisons
- Dust- and water-resistant frame
- Tool-less dovetail connection
- Inch scale only
- Description lists options not on this model
Performance notes
The lifting lever moves the spindle smoothly, and the frame has no through screw holes, which resists dust and water. The balanced dial shows deviation from a reference point rather than a direct size.
