Checking large shafts, housings and turned parts often means working close to machining operations where coolant and cutting oil are present. The Mitutoyo 293-255-30 is designed for these conditions with an IP65 protection rating. Its dust-tight construction and protection against water jets from any direction make it suitable for demanding machining and inspection environments.
The digital display provides a 0.001 mm resolution, allowing operators to read measurements directly without interpreting traditional mechanical graduations. The Digimatic output port allows measurements to be transferred directly to a compatible data processor, PC or SPC system, helping reduce manual transcription errors and supporting digital inspection workflows.
Consistent measuring force is important when measuring large components. Use the appropriate constant-force mechanism for this model and avoid forcing the thimble. Before measurement, establish the micrometer origin against a suitable reference standard at the minimum range length.
Before ordering, confirm the required measuring range, display units, Digimatic data-output requirements and preferred configuration. General Tech can assist with model selection and calibration requirements.

Frequently Asked Questions
What is the measuring range of the Mitutoyo 293-255-30?
The measuring range is 225–250 mm with a 0.001 mm resolution.
What does IP65 mean for the Mitutoyo 293-255-30?
IP65 indicates that the micrometer is dust-tight and protected against water jets from any direction. This makes it suitable for measurement environments where coolant and cutting oil are present.
Does the Mitutoyo 293-255-30 have data output?
Yes. It has Digimatic data output for sending measurements to a compatible data processor, PC or SPC system.
What is the advantage of Digimatic data output?
It allows measurements to be transferred electronically, helping reduce manual transcription and supporting digital inspection and SPC workflows.
How should I apply measuring force when using this micrometer?
Use the appropriate constant-force mechanism for the model and avoid forcing the thimble. Consistent measuring force helps improve measurement repeatability.
Should I choose the 293-255-30 or the 293-256-30?
The 293-255-30 covers 225–250 mm, while the 293-256-30 covers 250–275 mm. Select the model whose measuring range matches the component being measured.
