Description
Product Overview
The outside micrometer is the single most-used precision tool in any serious workshop — and the 0-25mm range is the one you’ll reach for more often than any other. The Mitutoyo 293-234-30 is the current-generation evolution of the legendary QuantuMike / Digimatic IP65 coolant-proof micrometer line, combining Mitutoyo’s signature ABSOLUTE encoder with IP65 coolant-resistant sealing. That means it can live on a wet machining centre bench, get splashed with coolant, soap, and cutting oil, and still hold ±2μm accuracy year after year. Brand new, factory sealed, with inspection certificate.
- ABSOLUTE (ABS) scale technology — the micrometer never loses its origin point. Switch it on and it already knows zero, no re-zeroing after every power-cycle.
- 0-25mm range with 0.001mm resolution.
- ±2μm accuracy across the full range — genuine metrology-grade, not the ±5μm+ drift you’ll see on cheap digital mics.
- IP65 coolant-proof rating — fully sealed against splashing coolant, cutting oil, and workshop grime. Built for the shop floor, not just the inspection room.
- Ratchet stop applies consistent measuring force every time, eliminating operator variability between readings.
- SPC Digimatic data output for connecting to Mitutoyo data collectors and QC software.
- Ideal for general machining, toolmaking, QC inspection, shaft and pin measurement, turned-part verification, and any application where a reliable digital outside reading matters.
Condition
New (Factory Sealed).
This 293-234-30 is brand new, unopened, and still in its factory-sealed Mitutoyo packaging. Tamper seals intact, genuine Mitutoyo hologram authentication present — worth noting given the sheer volume of counterfeit Mitutoyo micrometers circulating online. Inspection certificate, user manual, battery, and standard reference bar are all packed inside the original fitted case. Straight onto the bench and ready to work.
Included:
- 1 x Mitutoyo 293-234-30 Digital Micrometer, 0-25mm
- Reference standard bar (where applicable — 25mm models typically don’t include one, as zero-setting is done directly on the anvils)
- Fitted storage case
- Inspection certificate
- User manual
- Battery (installed)
- Spanner for zero adjustment
Brand Information
Mitutoyo is the global benchmark in precision metrology — founded in Tokyo in 1934 and now the default specification on virtually every engineering drawing worldwide. The 293-series Digimatic micrometer range has been the industry reference for digital outside micrometers for decades, with the current IP65 coolant-proof generation representing the refinement of a tool that was already the standard. Buying a genuine, sealed Mitutoyo 293-234-30 means you’re getting real ABS encoder hardware and factory calibration — not a visually-similar clone with inferior internals masquerading as the real thing.
