Description
Product Overview
The Mitutoyo 500-153 is a 300mm Absolute Digimatic digital calliper — a long-range precision measuring tool built to Japanese toolroom standards. With a 300mm measuring range and Mitutoyo’s ABSOLUTE encoder technology, this calliper holds its last reading even after power-off, eliminating the need to re-zero from a closed position every time you switch on. It’s a reliable, no-nonsense bench instrument suited to larger workpieces where a standard 150mm calliper simply won’t reach.
- ABSOLUTE Encoder Technology — Unlike conventional incremental encoders, the ABSOLUTE system retains position reference without a battery backup circuit actively running. Power the unit on mid-stroke and the reading is immediately valid. On a busy shop floor where instruments get switched off between jobs, this removes a common source of gross measurement error.
- 300mm Measuring Range — Covers outside, inside, depth, and step measurements up to 300mm in a single instrument. This is the sweet spot for checking larger turned components, fabricated frames, or weldments that exceed the capacity of a standard 150mm calliper without stepping up to a full bench micrometer or CMM.
- 0.01mm Resolution, Digital Readout — The LCD display reads directly in millimetres at 0.01mm resolution. There’s no vernier interpolation required, which reduces reading error — particularly useful when checking dimensions quickly under workshop lighting or when handing the tool to an apprentice.
- Stainless Steel Beam and Hardened Jaws — The beam and jaw faces are hardened stainless steel, resisting wear on the measuring faces and corrosion from cutting fluid contact. Jaw alignment is critical on a long-beam calliper; hardened faces maintain their geometry under repeated use far better than softer alternatives.
- Ideal for — Checking turned diameters on larger lathe work, measuring bore depths on pump housings and gearboxes, verifying stock material lengths before sawing, outside diameter checks on large-diameter pipe and hollow sections, and step measurements on fabricated weldments and platework.
Condition
Used (Good Condition / Regular Workshop Use)
This calliper presents in honest, functional workshop condition consistent with regular professional use. The jaw faces align squarely when closed — there’s no visible jaw splay or twist, which is the key functional check on any used calliper of this beam length. The beam shows the expected light surface patina and minor handling marks you’d expect from a tool that’s been earning its keep on a bench, but there is no evidence of impact damage, dropped-tool distortion, or jaw face pitting from misuse. The digital readout functions correctly and the ABSOLUTE encoder retains position as designed. The seller confirms accuracy is sound; as with any used precision instrument, we recommend verifying zero against a known reference (a slip gauge or ground reference block) and checking jaw parallelism over the full travel before putting it into critical production use. That’s standard practice for any pre-owned measuring instrument, regardless of brand.
