Description
Product Overview
The Mitutoyo 570-223 Digimatic HDS Height Gauge is a 300mm capacity digital height gauge built for serious surface plate and toolroom work. Driven by Mitutoyo’s linear encoder technology, it delivers direct digital readout without the parallax error or interpolation guesswork of a vernier column — a genuine advantage when you’re scribing part datums, checking step heights on machined castings, or qualifying a batch of turned components against a drawing tolerance. This is a proper Japanese-made instrument, not a budget import, and it belongs on any bench where repeatable height measurement actually matters.
- Linear encoder with 0.01mm resolution — The HDS series uses an electrostatic linear encoder rather than a rack-and-pinion potentiometer, giving you stable, drift-free readings as you traverse the column. At 0.01mm (roughly half a thou) resolution, you’re splitting tolerances that a vernier column can only approximate.
- ZERO/ABS and PRESET functions — The ability to zero at any datum point or preset a target value means you can work directly in incremental mode off a machined shoulder or reference surface without resetting to zero every time — critical when checking multiple features from a single datum on a surface plate.
- Granite-compatible hardened base — The cast iron base is precision ground on its underside to sit stable and square on a surface plate or master flat. A rocking or under-ground base is the primary source of height gauge error; the Mitutoyo casting geometry addresses this directly.
- DATA OUTPUT port — The onboard OUTPUT button allows connection to Mitutoyo’s Digimatic interface (SPC cable, sold separately) for direct feed into a statistical process control system or PC logging setup — relevant for any shop running documented inspection routines or ISO 9001 QMS requirements.
- Ideal for — Surface plate layout and scribing, incoming goods inspection on machined parts, step height verification on milled components, checking bore depths and shoulder positions on turned parts, qualifying parallels and angle plates, and setting tool height references in toolroom and gauge room environments.
Condition
Used (Good Condition / Workshop Patina)
This gauge presents as a used toolroom instrument that has seen genuine service. The digital readout head functions, and the Digimatic display, keypad buttons (ON/OFF, ZERO/ABS, PRESET, HOLD, +/–, OUTPUT), and thumb-wheel fine adjust all appear present and operable as visible in the product photograph. The stainless steel beam shows typical handling marks and light surface scratching consistent with regular bench use — this is cosmetic patina only and does not affect the accuracy of the linear encoder, which reads from the internal scale rather than the external beam surface. The scriber arm is present and appears to be the standard offset scriber blade. The precision-ground base shows no visible damage or significant wear that would compromise its seating on a surface plate. As with any used precision instrument, the buyer should verify the gauge against a known reference — zeroing against a calibrated gauge block stack or checking repeatability against a precision parallel on a surface plate is straightforward and strongly recommended before committing the tool to production inspection. If the application demands traceable calibration, budget for a NATA-accredited cal check after purchase.

Brand Information
Mitutoyo Corporation, founded in Japan in 1934, is the global benchmark in precision metrology instrumentation — the name sits in the same tier as Mahr, Starrett, and Brown & Sharpe, and in many product categories, Mitutoyo sets the standard those peers are measured against. Their instruments are manufactured to exacting tolerances in Japan and are found in toolrooms, gauge rooms, and on surface plates in precision engineering facilities worldwide, including throughout Australian aerospace, defence, and automotive manufacturing supply chains. Buying a used Mitutoyo is a fundamentally different proposition to buying a new import of uncertain provenance — the underlying instrument quality and part availability give it a long service life even after years of workshop use.
