Description
Product Overview
The 543-400B is Mitutoyo’s workhorse digital dial indicator: 12.7 mm range, 0.01 mm resolution, delivered in a compact, shop-proven body that’s earned its place on toolroom benches across the globe. This unit presents in good used condition with verified function.
- ABSOLUTE Encoder Technology — no re-zeroing after power loss. Unlike conventional incremental encoders that forget their position the moment the display sleeps, the ABSOLUTE capacitive encoder retains origin data indefinitely. On a busy shop floor where the indicator gets knocked, pocketed, or powered down between setups, this is a genuine time-saver and error-eliminator.
- 0.01 mm Resolution over a 12.7 mm Range — readable at a glance under fluorescent shop lighting. The large LCD delivers a clear numeric readout without the parallax error inherent in analogue needle indicators, making it reliable for checking four-jaw chuck setups, lathe tailstock alignment, and press-fit interference verification where you need a definitive number, not an estimated needle position.
- 8 mm Stem (Shank) Diameter — fits the overwhelming majority of indicator holders, magnetic bases, and tooling arms. The standardised 8 mm stem means the 543-400B drops straight into most Noga, Kanetop, and generic dial indicator holders without needing adaptors — critical when you’re mid-setup and adaptor hunting is not on the agenda.
- mm / inch Switchable via MODE button — one tool for both drawing standards. Particularly useful in Australian job shops working across metric-native and legacy imperial drawings, or when verifying against imported tooling with inch callouts.
- Ideal for: tramming mill heads and vices square, four-jaw chuck centring, lathe spindle and tailstock runout checks, surface grinder table flatness traverses, press and assembly datum verification, and CMM probe qualification checks.
Condition
Used (Good Condition / Verified Functional)
The display is clean and fully legible with no dead segments or flickering observed. The measuring spindle travels smoothly through its full 12.7 mm range without stiction or binding, and returns consistently under spring pressure — the key functional test for any plunger-type indicator. The stem and contact point show the expected patina of shop use: minor surface marks consistent with indicator holder clamping are present on the 8 mm shank, and there is light general wear to the body finish, but no dents, cracks, or damage to the front bezel or display face. The contact point tip shows wear consistent with normal use and may benefit from replacement before critical measurement work — Mitutoyo replacement contact points (flat, ball, and carbide options) are inexpensive and widely stocked. As with any used precision instrument, verification against a known standard — a gauge block stack or calibrated ring gauge — is recommended before placing the unit into a production environment. For toolroom setup, runout checking, and general comparative measurement, the gauge performs as expected.
Included:
- 1 x Mitutoyo Digital Dial Indicator 543-400B (12.7 mm range / 0.01 mm resolution, mm/inch)
Not included: Original carry case, calibration certificate, spare battery, indicator holder or magnetic base. A standard SR44 / 357 silver oxide cell is required if the battery is depleted.
Brand Information
Mitutoyo Corporation, founded in Japan in 1934, is the benchmark name in precision metrology — the brand that toolmakers, quality engineers, and NATA-accredited laboratories reach for when accuracy is non-negotiable. Manufactured in Japan to exacting tolerances, Mitutoyo instruments sit at the top tier of the global metrology market alongside Mahr, Tesa, and Starrett, and consistently outperform generic OEM alternatives in long-term repeatability and build quality. In Australian trade and toolroom environments, Mitutoyo is the de facto standard — a used Mitutoyo instrument in good working order retains genuine shop-floor credibility that no-name equivalents simply cannot match.
