The Mitutoyo 293-240-30 Digital Micrometer 0-25mm gauges external thicknesses with 0.001mm resolution. A ratchet stop applies uniform pressure for ±1 µm accuracy across the entire measuring range. This updated version increases battery longevity to 2.4 years from the 1.2-year capacity found in the previous 293-240 model.

- IP65 Protection Level: Housing resists water jets and road dust. Circuitry stays functional in humid shop environments.
- Carbide-Tipped Faces: Hardened contact points resist surface friction wear. Parallelism stays within 1 µm for consistency.
- SR44 Power Supply: Small button cell lasts for 2.4 years. Replaces the 1.2-year limit of older models.
- LCD Digital Display: Screen shows values in 0.001mm increments. Stops parallax errors found on manual thimbles.
Frequently Asked Questions
Is Mitutoyo 293-240-30 waterproof?
The IP65 rating protects internal components against splashing water and dust. Submerging the tool will cause permanent electronics failure.
How to calibrate Mitutoyo digital micrometer?
Close the measuring faces and press the zero button. Use a 25mm gauge block to verify the ±1 µm accuracy.
